Question

please explain, thanks

1a. The equilibrium for the formation of HOCl in the gas phase from chlorine dioxide (C120) is given below. What are the expected equilibrium pressures if a cylinder has initial pressures as follows: PC120 = PH20 = 0.45 atm; Phoci = 0.65 atm ? (10 points) Cl20 (g) + H2O (g) = 2 HOCl2 (g) Kp=0.085 at 395 °C 1b. Does the total pressure in the cylinder increase, decrease or remain the same as the reactions goes from its original condition to equilibrium ? Provide a brief statement that supports your prediction. (6 points)
