Question
At 500 K, the Kp of the reaction PCI5 (g) = PCI3 (g) + Cl2 (g) is 0.497. In a chamber
at 500 K, we mix the gases, and their partial pressures are given by P (PCI5(g)) =
0.325 atm, P(PCI3 (g)) = 0.132 atm and P(Cl2(g)) = 0.241 atm.
Which of the following statements is/are correct regarding how the mixture will
proceed to reach equilibrium?
a) The partial pressure of PCI3 will increase during the reaction course to reach
equilibrium.
b) The partial pressure of PCI5 will increase during the reaction course to reach
equilibrium.
c) The reaction Gibbs energy change AG is less than zero for the above
condition: P (PCI5(g)) = 0.325 atm, P(PCI3 (g)) = 0.132 atm and P(Cl2(g)) = 0.241
