Chapter EQ, Problem 30PQ

Interpretation Introduction

Interpretation:

The value of ΔG at 1000 K has to be calculated.

Concept introduction:

Free energy change${\text{ΔG}}^0$: The change in the free energy takes place while reactant converts to product where both are in standard state. It depends on the equilibrium constant $\text{K}$.

  ${\text{ΔG}}^{\text{0}}\text{=}-\text{RT}\left(\text{ln}\text{K}\right)\text{=}{\text{ΔH}}^{\text{0}}-{\text{TΔS}}^{\text{0}}$

  Where $\text{T}$ is the temperature

The formula of $\text{ΔH}$ in terms of $\text{ΔG}$ and $\text{TΔS}$ is,

    $\text{Δ}{\text{H}}^{\text{o}}\text{=}\text{Δ}{\text{G}}^{\text{o}}\text{+T}\text{ΔS}$
