Chapter 16, Problem 77E

Interpretation Introduction

Interpretation: The reaction corresponding to the formation of ${\text{NF}}_{\text{3}}$ and partial pressure of ${\text{N}}_{\text{2}},{\text{F}}_{\text{2}}$ and ${\text{NF}}_{\text{3}}$ is given. The value of $\Delta G°$ is to be calculated at given temperature.

Concept introduction: Equilibrium constant, $K$, is defined as the ratio of the concentration of products to that of the reactants at equilibrium. If a given reaction is at equilibrium, then the free energy change will be,

$\begin{array}{c}\Delta G=\text{0}\\ Q=K\end{array}$

The expression for free energy change is,

$\Delta G°=-RT\ln \left(K\right)$
