The equilibrium constant Kp for the reaction

is 1.05 at 250°C. The reaction starts with a mixture of PCl5, PCI3, and Cl2 at pressures of 0.177,0.223. and 0.111 atm. respectively, at 250°C. When the mixture comes to equilibrium at that temperature, which pressures will have decreased and which will have increased? Explain why.
