First, we need to write the expression for the equilibrium constant, Kc: Kc = [N₂][H₂O]^2 / [NO]^2[H₂]^2 Then we can plug in the given equilibrium concentrations and solve: Kc = (1.2)(2.0)^2 / (0.75)^2(0.50)^2 Kc = 34 Therefore, the equilibrium constant for this reaction is 34, so the best choice is C.
