Problem

Consider the following reaction at a certain temperature. 

2H2O (g) ⇌ 2H (g) + O2 (g)

An equilibrium mixture of the reaction at that same temperature was found to contain 0.416 M of water vapor, H2O, 0.398 M oxygen gas, O2, and 0.472 M hydrogen gas, H 2. Determine the value of the equilibrium constant, Kc, for this reaction.
