Equilibrium Constants are Affected by Temperature Changes

Question:
How would the value of the equilibrium constant, k, be affected if the reaction was heated by 1000°c?
(a) if the reaction was endothermic
(b) if the reaction was exothermic

Answer:
(a)  For an endothermic reaction, an increase in temperature will increase the value of the equilibrium constant.
(b) For an exothermic reaction, an increase in temperature will decrease the value of the equilibrium constant.
