Given that at equilibrium $[ \mathrm { A } ]$ =0.072 M and $[ \mathrm { B } ]$ =0.089 M at 40 ${ } ^ { \circ } \mathrm { C }$ , calculate the equilibrium constant $K$ from the equilibrium concentrations for the reaction $A ( g ) f \quad B ( g )$ .

Question

Quizplus · Accepted Answer

The equilibrium constant $K$ for the reaction $A ( g ) \rightleftharpoons B ( g )$ is calculated using the formula $K = \frac{[B]}{[A]}$. Substituting the given concentrations, $K = \frac{0.089}{0.072} = 1.23$.
