Chapter 18, Problem 58AP

Interpretation Introduction

Interpretation:

The possible reasons for no reaction, occurring between given different compoundsin the container, after 1 week are to be identified.

Concept introduction:

The spontaneity of areaction is determined by Gibbs free energy. The mathematical equation is expressed as follows:

$\Delta G=\Delta H-T\Delta S$

Here, $\Delta G$ is Gibbs free energy, $\Delta H$ is the enthalpy of the reaction, $T$ is temperature and $\Delta S$ is entropy.

$\Delta G$ can predict the spontaneity of the reaction as follows:

If $\Delta G<\text{0}$, the system is spontaneous in the forward direction.

If $\Delta G=\text{0}$, the system is in equilibrium.

If $\Delta G>\text{0}$, the system is non-spontaneous in the forward direction.
