Answer:
If the forward reaction is endothermic,
The equilibrium position will shift right, and the equilibrium constant Kc will increase.
Increasing the temperature (heating) for a reaction will increase the rates of both the forward and backward reactions, but it will increase the rate of endothermic reaction to a greater extent.
Since the forward reaction is endothermic, heating will cause the rate of forward reaction higher than that of the backward reaction, meaning more CO2 will be formed. The equilibrium position thus shifts right.
As more CO2 is formed, its concentration increases. Hence, the equilibrium constant also increases.
