20) The equilibrium constant, Kp, is 6.3105 at 1500K for the reaction represented below. A chemist mixed 55%CH3Cl(g) and 45%HCl(g) by moles into a rigid container until the total pressure inside the container was 1.5atm at 1500K. HCl(g)+CH3Cl(g)CH4(g)+Cl2(g) a. Find the initial partial pressures of each gas. b. Find the equilibrium partial pressures of each gas at 1500K. c. The temperature of the system changed, and the equilibrium constant, Kp, became 4.71010. Find the new partial pressures of all gaseous species at equilibrium
