calculate δg at 298 k for the given process: c2h5oh(l) → c2h5oh(g) if the partial pressure of c2h5oh(g) is 0.0263 atm and δg° = 6.2 kj/mol at 298 k and 1 atm = 1.
a. 6.2 KJ
b. 2.8 KJ
c. -15 KJ
d. 15 KJ
e. -2.8 KJ

Answers

Answer 1

We can use the equation ΔG = ΔG° + RTln(Q) to calculate the change in Gibbs free energy for the given process, where ΔG° is the standard Gibbs free energy change, R is the gas constant (8.314 J/K mol), T is the temperature (298 K), and Q is the reaction quotient. Option C is correct.

First, we need to calculate the reaction quotient, Q. For the given process, the balanced chemical equation is:
C2H5OH(l) → C2H5OH(g). Since there is only one reactant and one product, Q is simply the partial pressure of C2H5OH(g): Q = PC2H5OH(g) = 0.0263 atm

Next, we can plug in the values into the equation:
ΔG = ΔG° + RTln(Q)
ΔG = (6.2 kJ/mol) + (8.314 J/K mol)(298 K) ln(0.0263 atm)
ΔG = 6.2 kJ/mol - 16.81 kJ/mol
ΔG = -10.61 kJ/mol

Therefore, the change in Gibbs free energy for the given process is -10.61 kJ/mol, which corresponds to answer choice (c) -15 kJ.

Answer 2

The answer is e. -2.8 KJ. Therefore, the actual Gibbs free energy change (ΔG) at 298 K is -2.8 kJ/mol.

The formula for calculating the standard Gibbs free energy change (ΔG°) is:

[tex]ΔG° = -RT ln K[/tex]

where R is the gas constant (8.314 J/mol•K), T is the temperature in Kelvin, and K is the equilibrium constant.

To calculate the actual Gibbs free energy change (ΔG), we use the formula:

[tex]ΔG = ΔG° + RT ln Q[/tex]

where Q is the reaction quotient, which is the ratio of the product of the concentrations of the products raised to their stoichiometric coefficients to the product of the concentrations of the reactants raised to their stoichiometric coefficients. When dealing with gases, we can use partial pressures instead of concentrations.

In this case, the reaction is:

[tex]C2H5OH(l) → C2H5OH(g)[/tex]

At equilibrium, the partial pressure of C2H5OH(g) is 0.0263 atm. The reaction quotient is therefore:

Q = P(C2H5OH)/P° = 0.0263/1 = 0.0263

Substituting the values into the formula, we get:

ΔG = ΔG° + RT ln Q

= 6.2 kJ/mol + (8.314 J/mol•K)(298 K) ln 0.0263

= -2800 J/mol

= -2.8 kJ/mol

Therefore, the actual Gibbs free energy change (ΔG) at 298 K is -2.8 kJ/mol.

Firefighters must handle the area as a medical emergency incident in addition to a fire scene. The victim should be treated as evidence and kept in tact.

Why is it difficult to find evidence of arson?

All unintentional causes of a fire-related incident must be eliminated before it can be deemed arson; this requires strong evidence that the fire was started intentionally. Arson is challenging to establish and later prosecute for this reason.

Why is fire investigation difficult?

For three key reasons, arson investigations are challenging: The arsonist can prepare the fire in advance and bring all the necessary equipment with them. There is no requirement that the arsonist be present while the act is committed. Evidence linking the arsonist to the crime is destroyed by the fire itself.

The initial concentration in the reaction mixture will contain [A] = 0.1 M and [B] = 1.0 M

Below is the reaction

A(g) → B(g)

And the equilibium constant will be explained in terms of [A] and [B]:

Keq = 10 = [B]/[A]

If the first conditions are that [A] = 1.1 M and [B] = 0.0 M, the conditions at equilibrium is:

[A] = 1.1M - x

[B] = 0.0M + x

Now we rewrite Keq:

Keq = 10 = [0.0 +x] / [1.1 -x]

at the end we got it  for x:

10 = [0.0 +x] / [1.1 -x]

10 * (1.1-x) = x

What is titration?

Titration is a quantitative analytical procedure that works by allowing a known analyte to gradually react with a titrant until an endpoint is reached.

Titration for weak acid and strong base:

Moles of acetic acid =  moles of NaOH

Given:

Concentration of NaOH = 0.1067 M

Volume of NaOH = 30.07 ml = 0.03007 L

Calculation:

So, by using the formula, Concentration = Moles/Volume

Moles of NaOH = concentration x volume = 0.1067 x 0.03007 = 0.0032

Therefore, the moles of acetic acid  = 0.0032 mole

Why is it difficult to see whether you have added the phenolphthalein to the flask solution before you have titrated it? ​

Answers

Whether in an alkali (pink) or an acid (colorless) solution, the phenolphthalein indicator has one of two distinct structures. Both structures are light-absorbing in the ultraviolet spectrum, which the human eye cannot see. So it is challenging.

What is phenolphthalein? The phthalein family of chemical compounds includes the indicator phenolphthalein (C20H14O4). The powder is a thin, crystalline yellowish-white to light orange powder. It has a pKa of 9.3, is barely soluble in water, and, when dissolved in alcohol, is used as an indicator for acid-base titration investigations.It is colorless in liquid form until pH 8.5 when it transforms from pink to dark red. Adolf von Baeyer, a German chemist, created phenolphthalein in 1871. He produced it by fusing phenol and phthalic anhydride in the presence of sulfuric acid (H2SO4) or zinc chloride. Phenolphthalein is closely linked to the triphenylmethane dyes (ZnCl2). The abbreviation "HIn" or "php" in shorthand notation is frequently used to refer to the chemical compound phenolphthalein, which has the formula C20H14O4. Its structure consists of 2 alcoholic groups, one ketone group, three hexagonal structures, and one pentagonal structure. Another compound with carbon, hydrogen, and oxygen chain structure is phenolphthalein.Phenolphthalein is frequently used as an indicator in acid-base titrations. Due to its water solubility, phenolphthalein is frequently dissolved in alcohols before use in experiments. It is a weak acid that can lose H+ ions in solutions. While the ion of phenolphthalein is purple, the phenolphthalein molecule is colorless.A common indicator used in titration experiments to show the titration's endpoint is phenolphthalein, an inert, colorless acid. Since this molecule dissociates to generate pink anions when dissolved in water, the endpoint is signaled by the production of pink color.

Given:

Molarity of KOH = 0.0849 M

Volume = 42.35 mL = 42.35 / 1000 = 0.04235 L

Mole of KOH = Mole = Molarity x Volume

HA + KOH → KA + H₂O

From the above equation, A mole of HA and a mole of KOH react together. Therefore,

0.00359 moles of HA will also react with 0.00359 moles of KOH.

0.00359  moles of base use = 1/1 x 0.00359 = 0.00359 moles of HA

An increase in __________ will directly stimulate the peripheral chemoreceptors to increase ventilation.

Answers

An increase in pH will directly stimulate the peripheral chemoreceptors to increase ventilation.

Chemoreceptor can be stimulated by change in the chemical composition of their immediate environment .There are many types of chemoreceptor spread throughout the body which help to control different process including taste, smell and breathing. An increase in body temperature increases the rate from peripheral chemoreceptor neurons.

The chemoreceptor is also known as chemosensor. The chemoreceptor is a specialized sensory receptor which transduces a chemical substance ( endogenous or induced ) to generate a biological signal. The two types of chemoreceptor is peripheral and central.

The formation constant for the reaction ag (aq) 2nh3(aq) ag(nh3)2 (aq) is kf = 1.7 × 107 at 25°c. what is δg° at this temperature? (r = 8.314 j/k• mol)?

Answers

The value of ΔG° at this temperature is -18034.18 J/mol

Calculation,

Given information

formation constant (Kf)= 1.7 × [tex]10^{7}[/tex]

Universal gas constant (R) = 8.314 J/K• mol

Temperature = 25° C = 25 °C + 273 = 300 K

Formula used:

ΔG° = -RT㏑Kf

By putting the valur of R,T, Kf we get the value of ΔG°

ΔG° = - 8.314 J/K• mol×300K㏑ 1.7 × [tex]10^{7}[/tex]

ΔG° = -2494.2㏑ 1.7 × [tex]10^{7}[/tex] = -18034.18 J/mol

So, change in standard Gibbs's free energy is -18034.18 J/mol
