Chapter 6, Problem 54IP

Interpretation Introduction

Interpretation:

From the given options, the correct one which must be true for the reaction with $\Delta G<0$ has to be identified.

Concept introduction:

The Gibbs free energy or the free energy change is a thermodynamic quantity represented by $\Delta G$. The expression for the free energy change with respect to the $K_{eq}$ is written below,

 $\text{ΔG}={\text{-RTlnK}}_{\text{eq}}$  where, R is the gas constant, T is the temperature in Kelvin.

If $\Delta G<0$ then the reaction is spontanous in forward reaction and so the reaction will favor products.

If $\Delta G>0$ then the reaction is spontanous in backward reaction and so the reaction will favor reactants.

If $\Delta G=0$ then the reaction is at equilibrium.
