The Effect of a Temperature Change on Equilibrium
The following reaction is endothermic:
CaCO_3(s) \rightleftharpoons CaO(s)+ CO_2(g)
What is the effect of increasing the temperature of the reaction mixture? Decreasing the temperature?
Since the reaction is endothermic, we can think of heat as a reactant:
heat +CaCO_3(s) \rightleftharpoons CaO(s)+ CO_2(g)
Raising the temperature is equivalent to adding a reactant, causing the reaction to shift to the right. Lowering the temperature is equivalent to removing a reactant, causing the reaction to shift to the left.
