The equilibrium constant, K p , is 7.6 10^ -16 at 1000 degrees * C for the reaction represented below. 2 H 2 O(g) =H 2 (g)+O 2 (g) a. Write the equilibrium expression, Kp, for the reaction. b. Suppose you start out with only H 2 O(g) in a rigid container, and its initial partial pressure is recorded to be 1.27 atm. What are the partial pressures of each species when the system reaches equilibrium?
