Chapter 13, Problem 46E

Interpretation Introduction

Interpretation:

Whether the value of ${\Delta }_r{S}^o$ for the reaction is positive or negative needs to be determined.

$\text{CO}\left(g\right)+{\text{H}}_{\text{2}}\text{O}\left(g\right)\to {\text{CO}}_2\left(g\right)+{\text{H}}_2\left(g\right)$

Concept introduction:

Entropy represents the randomness of a system. A gaseous molecule has more entropy compare to solid and liquid molecules. The standard entropy changes for a reaction can be calculate with the help of standard molar entropy of reactant and product.

$\text{ΔrS°= }\Sigma \text{ΔrS°product - }\sum \text{ΔrS°reactant}$
