Question 1

For the reaction:

PCl3(g) + Cl2(g) PCl5(g) at 85 °C, Kp = 1.19

If one starts with 2.00 atm pressure of PCl3, 1.00 atm pressure of Cl2 and no PCl5, what is the partial pressure of PCl5(g) at equilibrium?
◦ 0.167 atm
◦ 0.739 atm
◦ 0.621 atm
◦ 0.465 atm
◦ 0.553 atm

Question 2

For the reaction: 2 Cl2(g) + 2 H2O(g) 4 HCl(g) + O2(g), Kp = 6.4 × 10-6 at 500 K. If a fixed volume is filled with initial concentrations of these gases at 227 °C such that [Cl2] = 0.5 M, [H2O] = 0.40 M, [HCl] = 0.5 M, and [O2] = 0.015 M, in which direction will the reaction proceed?
◦ The reaction proceeds to the right.
◦ The reaction proceeds to the left.
◦ The reaction is already at equilibrium.
◦ The reaction volume must be specified to answer this question.
◦ The value of Kp at 25 °C must be specified to answer this question.
