Chapter 9, Problem 9.23P

Interpretation Introduction

Interpretation:

The signs of $\Delta H$, $\Delta S$ and $\Delta G$ for the given spontaneous reaction needs to be determined.

Concept introduction:

The entropy is defined as randomness in the system. For a system with more gaseous species, the randomness is more as compared to liquid and solid species. Also, for a spontaneous reaction, the sign of $\Delta G$ is always negative.

The relation between $\Delta G$, $\Delta S$ and $\Delta H$ is represented as follows:

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