1. Consider the reaction below: 2 H2S (g) 2 H2 (g) + S2 (g) Kp = 2.4 x 10-4 (at 1073 K) a) A reaction mixture contains 0.112 atm of H2, 0.055 atm of S2, and 0.445 atm of H2S. Is the reaction mixture at equilibrium? If not, in what direction will the reaction proceed? b) Set up the ICE table that you would use to calculate the equilibrium partial pressures of all gases in the reaction and set up the expression for Kp in terms of equilibrium partial pressures but do NOT solve.
