Chapter 7, Problem 7.80P

Interpretation Introduction

Interpretation:

The equilibrium concentrations of NH₃ should be determined when the equilibrium concentrations of H₂ and N₂ are given.

Concept introduction:

The given equilibrium reaction representing the formation of NH₃ from N₂ and H₂ ,

${\text{N}}_2(g)+3{\text{H}}_2(g)◰\hspace{1em}2{\text{NH}}_3(g)$

Equilibrium constant, K for this reaction can be determined using the equilibrium molar concentrations of H₂, N₂ and NH₃ as below,

$\text{K=}\frac{{{\text{[NH}}_3\text{]}}^2}{{\text{[N}}_{\text{2}}{\text{][H}}_2{]}^3}$.
