Chapter 18, Problem 18.133MP

Interpretation Introduction

Interpretation:

Standard molar entropy for ${\text{O}}_{\text{2}}$ is to be calculated.

Concept introduction:

The expression to evaluate $\Delta H°$ is as follows:

$\Delta H°=\Delta H_{\text{f}}{°}_{\text{(products)}}-\Delta H_{\text{f}}{°}_{\text{(reactants)}}$

Where,

• $\Delta H_{\text{f}}{°}_{\text{(products)}}$ denotesstandard enthalpy for formation of products.
• $\Delta H_{\text{f}}{°}_{\text{(reactants)}}$ denote standard enthalpy for formation of reactants.
• $\Delta H°$ denotesstandard enthalpy change that accompanies overall reaction.
