Question

The equilibrium constant for the reaction $2HI(g) \rightleftharpoons H_2(g) + I_2(g)$ is $0.014$ at $698\text{ K}$. What is the value of $K$ for the reverse reaction $H_2(g) + I_2(g) \rightleftharpoons 2HI(g)$?

Answer: B

💡 Solution & Explanation

Reversing a chemical equation results in an equilibrium constant that is the reciprocal of the original. $K_{reverse} = 1 / 0.014 = 71.4$.
