1. For the following reaction at equilibrium is a reaction vessel, which one of these changes would cause the I2 concentration to increaase? 2NOI(g) <---> 2NO(g) + I2(g) delta H rxn = 45.3 kL/mol 2. Ammonium iodide dissociates reversibly to ammonia and hydrogen iodide. NH4I(s) <---> NH3(g) + HI(g) At 400 degree Kp = 0.0215. Calculate the partial pressure of ammonia at equilibrium when a quantity of ammonium idodide in heated to 400 degree C.
