Question 1

A mixture, containing 0.0750 M HCl(g) and 0.0330 M O₂(g) is allowed to come to equilibrium at 480 °C.

4 HCl(g) + O₂(g)

2 Cl₂(g) + 2 H₂O(g)

At equilibrium [Cl₂] = 0.030 M. What is the value of K_c?
◦ 1.1 × 10^-3
◦ 890
◦ 0.13
◦ 1.3
◦ 480

Question 2

According to Le Chatelier's Principle:
◦ an increase in pressure always causes a change in the position of equilibrium for any reaction
◦ the greatest yield of ammonia in the exothermic reaction N₂ + 3 H₂

2 NH₃ is attained at a high temperature
◦ the equilibrium constant is increased for the reaction A + B

C if the concentration of A is increased
◦ an increase of temperature causes a decrease in the value of the equilibrium constant for an exothermic reaction
◦ when an equilibrium system is stressed, the system reacts to offset the stress
