2. the equilibrium constant kp for the reaction pcl5(g) ⇌ pcl3(g) + cl2(g) is 1.05 atm at 250ºc. the reaction starts with a mixture of pcl5, pcl3, and cl2 at pressures 0.177 atm, 0.223 atm, and 0.111 atm, respectively, at 250ºc. when the mixture comes to equilibrium at that temperature, which pressures will have decreased and which will have increased? explain why.
