81. Solving a chemistry problem

1. For the homogeneous gas reaction 4HCl O2↔2H2O 2Cl2, the initial amounts of HCl and O2 are 1 mol and 0.48 mol, respectively. Determine the equilibrium constant Kp at 600 K and a total pressure of 1.01105 Pa, if by the time equilibrium is established there is 0.402 mol of chlorine in the system.
