Chapter 18, Problem 107AP

Interpretation Introduction

Interpretation:

The $\Delta G$

for the given process at ${37}^{\circ }\text{C}$ is to be determined.

Concept introduction:

The free energy change of the reaction is related to the standard free energy according to the given equation:

$\Delta G = \Delta G^{\circ }+\text{R}T\ln Q$

Here, $\Delta G^{\circ }$

is the change in standard Gibbs free energy, $\Delta G$ is the free energy change of a system and $Q$

is the reaction quotient. $\text{R}$ is the universal gas constant, and $T$ is the absolute temperature.

The reaction is spontaneous if $\Delta G^{\circ }$ is negative.
