Chapter 7, Problem 7.73P

Interpretation Introduction

Interpretation:

The equilibrium concentrations of $\text{HF}$ should be determined.

Concept Introduction:

The given equilibrium reaction between H₂ and F₂ ,

${\text{H}}_2(g)+{\text{F}}_2(g)◰\hspace{1em}2\text{HF}(g)$

Equilibrium constant, K for this reaction can be determined using the equilibrium molar concentrations of H₂, F₂ and HF as below,

$\text{K=}\frac{{\text{[HF]}}^2}{[{\text{H}}_{\text{2}}{\text{][F}}_2]}$.
