Chapter 13, Problem 13F.2BE

Interpretation Introduction

Interpretation:

The electronic contribution to the molar Gibbs energy of ${\text{O}}_2$ atoms at $400\text{K}$ is to be calculated.

Concept introduction:

The valuable work at a constant pressure and temperature which is attained from a thermodynamic system is termed as the Gibbs free energy. It is denoted by $\Delta G$.

Gibbs free energy gives the feasibility of a reaction. If the equilibrium constant of the cell reaction is known, the value of standard EMF is calculated easily.

In a chemical process, the maximum quantity of work done is equivalent to the change in free energy.
