Chapter 17, Problem 76E

(a)

Interpretation Introduction

Interpretation: The standard Gibbs free energy $\left(\Delta G^{\text{ο}}\right)$ and the value of equilibrium constant $\left(K\right)$ for the given reactions are to be calculated at ${\text{25 }}^{\text{ο}}\text{C}$.

Concept introduction: Gibbs free energy is a thermodynamic quantity that is used to calculate the maximum work of reversible reaction performed by a system. It is equal to the difference between the enthalpy and the product of entropy at absolute temperature. Equilibrium constant is defined as the ratio of the concentration of products and the concentration of the reactants.

To determine: The standard Gibbs free energy $\left(\Delta G^{\text{ο}}\right)$ and the value of equilibrium constant $\left(K\right)$ for the given reaction at ${\text{25 }}^{\text{ο}}\text{C}$.
