Chapter 18, Problem 18.115SP

Interpretation Introduction

Interpretation:

The value of $\Delta G°$ for dissociation of ${\text{C}}_{\text{9}}{\text{H}}_{\text{7}}{\text{O}}_{\text{4}}{}^{-}$ is to be calculated.

Concept introduction:

The expression to evaluate free energy for a non-standard condition is as follows:

$\Delta G=-RT\ln K$

Where,

• $K$ represents equilibrium constant.
• $\Delta G°$ denote S the standard free energy change.
• $R$ denotes gas constant.
• $T$ denotes temperature.
