Practice ProblemATTEMPT

In an analysis of the following reaction at $\text{100°C}$,

$\text{Br2}\left(g\right){\text{ + Cl}}_{\text{2}}\left(g\right)\underset{}{\rightleftarrows }\text{ 2BrCl}\left(g\right)$

the equilibrium concentrations were found to be $\left[{\text{Br}}_{\text{2}}\right]\text{ = 2}\text{.3 }\times {\text{ 10}}^{\text{-3}}M{\text{, [C1}}_{\text{2}}\text{] = 1}\text{.2 }\times {\text{ 10}}^{\text{-2}}M$, and

$\left[\text{BrCl}\right]\text{ = 14 }\times {\text{ 10}}^{\text{-2}}M$. Write the equilibrium expression, and calculate the equilibrium constant for this reaction

at $\text{100°C}$.
