Chapter 5, Problem 5A.7E

Interpretation Introduction

Interpretation:

For the formation of ammonia, the reaction Gibbs energy has to be calculated and also direction of the spontaneous reaction has to be given.

Concept Introduction:

Gibbs energy and equilibrium constant:

The relationship between Gibbs energy and the equilibrium constant is given by,

$\begin{array}{l}{\text{Δ}}_{\text{r}}{\text{G}}^{\sout{\text{0}}}\text{=}\text{-}\text{R}\text{T}\text{ln}\text{K}\\ \text{where,}\\ {\text{Δ}}_{\text{r}}{\text{G}}^{\sout{\text{0}}}\text{-}\text{reaction}\text{Gibbs}\text{energy}\\ \text{K}\text{-}\text{equilibrium}\text{constant}\\ \text{R}\text{-}\text{gas}\text{constant}\text{and}\text{T}\text{-}\text{temperature}\end{array}$
