Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas: pcl3(g)+cl2(g)⇌pcl5(g). a 7.5-l gas vessel is charged with a mixture of pcl3(g) and cl2(g), which is allowed to equilibrate at 450 k. at equilibrium the partial pressures of the three gases are ppcl3 = 0.125atm , pcl2 = 0.155atm , and ppcl5 = 1.90atm kp= 98.1 what is kc?
