i need help for the three questions

Consider the following reaction: COCl2(g)[?1CO(g)+Cl2(g) If 1.09102 moles of COCl2,0.386 moles of CO, and 0.223 moles of Cl2 are at equilibrium in a 10.4L container at 748K, the value of the equilibrium constant, Kp, is The equilibrium constant, Kp, for the following reaction is 10.5 at 350.K. 2CH2Cl2(g)CH4(g)+CCl4(g) If an equilibrium mixture of the three gases in a 17.6L container at 350 . K contains CH2Cl2 at a pressure of 0.401 atm and CH4 at a pressure of 0.439atm, the equilibrium partial pressure of CCl4 is atm. The equilibrium constant, Kp, for the following reaction is 1.80102 at 698K. 2HI(g)H2(g)+I2(g) If an equilibrium mixture of the three gases in a 19.5L container at 698K contains HI at a pressure of 0.485atm and H2 at a pressure of 0.681 atm, the equilibrium partial pressure of I2 is atm
