Chapter 18, Problem 18.13P

Interpretation Introduction

Interpretation:

Standard free energy change for the give reaction is to be calculated and whether the reaction can be used for synthesis of acetylene is to be identified.

Concept introduction:

The expression to evaluate standard entropy is as follows:

$\Delta G°=\Delta G_{\text{f}}{°}_{\text{(products)}}-\Delta G_{\text{f}}{°}_{\text{(reactants)}}$

Where,

• $\Delta G_{\text{f}}{°}_{\text{(products)}}$ denotes free energy change for formation of products.
• $\Delta G_{\text{f}}{°}_{\text{(reactants)}}$ denote free energy change for formation of reactants.
• $\Delta G°$ denotes free energy change that accompanies overall reaction.
