Question 1
A mixture, containing 0.0750 M HCl(g) and 0.0330 M O
2(g) is allowed to come to equilibrium at 480 °C.
4 HCl(g) + O
2(g)
2 Cl
2(g) + 2 H
2O(g)
At equilibrium [Cl
2] = 0.030 M. What is the value of
Kc?
◦ 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 N
2 + 3 H
2 2 NH
3 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
