Chapter 20.4, Problem 20.11AFP

(a)

Interpretation Introduction

Interpretation:

The value of equilibrium constant for the given reaction needs to be calculated.

Concept Introduction:

The relation between change in standard Gibbs free energy of reaction and equilibrium constant is as follows:

  ΔGo=RTlnK

Here, R is Universal gas constant and T is temperature.

(b)

Interpretation Introduction

Interpretation: The value of change in Gibbs free energy of the reaction at 298 K needs to be calculated for given concentration values.

Concept Introduction: The relation between change in Gibbs free energy and change in standard Gibbs free energy is represented as follows:

  ΔG=ΔGo+RTlnQ

Here, R is Universal gas constant, T is temperature and Q is reaction quotient.

The reaction quotient for any reaction calculated by taking ratio of concentration of product species to the reactant species.

Consider the following general reaction: A(g) ⇌ B(g) Assuming that the ΔGo for this reaction is +50.2 J/mol, what is the equilibrium constant of this reaction at 420 K? (Please provide your answer to 3 significant figures.)
If the KP for the reaction CO(g) + H2O(g) ⇌ CO2(g) + H2(g) was calculated to be 3.32 × 103 at 298.15 K, at what temperature does KP = 5.00 × 103? What is the highest value that KP can have by changing the temperature? Assume that ΔHo is independent of temperature and that 1/∞ = 0.
Consider this reaction at 298 K: CO2 (g) + H2 (g) ⇌ CO (g) + H2O (g) Calculate ΔGrxn under the following conditions: PCO2 (g) = 0.198 atm; PH2 (g) = 0.252 atm; PCO (g) = 0.132 atm; PH2O (g) = 0.281 atm
