initially partial pressures (atm) 1.62 0 0
equilibrium partial pressures (atm) (1.62-x) x x
The equilibrium constant, Kp for the reaction is 0.636 at 600 K
By definition, Kp = (Pproducts)/(Preactant)
So we get for this reaction, Kp = {(PCO)(PCl2)}/PCOCl2)
PCO = PCl2 for this reaction. The partial pressures PCO and PCl2 are zero at the start. At equilibrium, let PCO = PCl2 = x atm
So, PCOCl2 = (1.62 - x) atm [ as total pressure is said to be 1.62 atm]
Putting the values in the expression for Kp, we get
0.636 = x2/(1.62 - x)
or, x2 + 0.636x -1.03 = 0
or, x= 0.746
So, at equilibrium, PCO = PCl2 = 0.746 atm , PCOCl2 = (1.62-.746) atm = 0.874 atm
