Chapter 7, Problem 7.53P

Interpretation Introduction

Interpretation:

The concentration of $\text{NOBr}$ at equilibrium should be determined when equilibrium concentration of $\text{NO}$ and ${\text{Br}}_{\text{2}}$ are each $0.80$

$\text{M}$ for the reaction $\text{2NOBr(g)}◰\hspace{1em}{\text{2NO(g)+Br}}_{\text{2}}\text{(g)}$ with equilibrium constant $25$

Concept Introduction:

Equilibrium constant may be defined as the ratio of concentrations of products to that of reactants.

Thus, ${\text{K}}_{\text{eq}}\text{=}\frac{\text{[Products]}}{\text{[Reactants]}}$

If value of ${\text{K}}_{\text{eq}}$ and any of the equilibrium concentrations of reactants and products are given then other can be calculated.
