Phosphorus trichloride gas and chlorine gas react to form phosphorus pentachloride gas.
PCl3(g) + Cl2(g) PCl5(g)
A gas vessel is charged with a mixture of PCl3(g) and Cl2(g), which is allowed to equilibriate at 450 K. At equilibrium the partial pressures of the three gases are PPCl3 = 0.124 atm, PCl2 = 0.157 atm, and PPCl5 = 1.30 atm.
(a) What is the value of Keq at this temperature?

Kp = p(PCl5)/p(PCl3)*p(Cl2)
Kp = 1.3/(0.124*0.157)
Kp = 66.78 approx.

You've turned the equation backwards, and doubled it. So you have to take the reciprocal of 0.112, and then square it. a is the answer.
