Question

Does equilibrium constant change with temperature?

Answer 1

Yes, the equilibrium constant varies with the change in temperature.

The equilibrium constant of an exothermic reaction decreases as the temperature decreases. However, in an endothermic reaction, the equilibrium constant increases with an increase in temperature.
