Chapter 19, Problem 82IAE

Interpretation Introduction

Interpretation:

The value of ${\Delta }_r{\text{G}}^0{\text{ for N}}_2{\text{H}}_4$ should be calculated.

Concept introduction:

In the special case in which the reactants and products are in their standard states; the standard Gibbs energy change per mole of reaction is given by the following relation:

${\text{Δ}}_{\text{r}}{\text{G}}^{\text{0}}{\text{ = -zFE}}^{\text{0}}{}_{\text{cell}}$

${\text{Δ}}_{\text{r}}{\text{G}}^{\text{0}}$ = ${\text{ΔG}}^{\text{0}}$ (products) - ${\text{ΔG}}^{\text{0}}$ (reactants)
