Solve the below problem:
Q: A mixture of 1 mol of H2O, 2 mol of O2, and 5 mol of N2 is heated to 2200 K at a pressure of 5 atm. Assuming the equilibrium mixture consists of H2O, O2, N2, and H2, determine the equilibrium composition at this state. Is it realistic to assume that no OH will be present in the equilibrium mixture?
