In exothermic reactions, increase in temperature decreases the equilibrium constant, K. While in endothermic reactions, increase in temperature increases the K value.

The equilibrium will shift to the left, making more of the reactants. This is because the reaction is endothermic in the reverse direction since it is exothermic in the forward direction. The system will try to absorb the energy input from the increased temperature by creating an endothermic reaction, a reaction that absorbs energy. The system does this in an attempt to make the conditions as similar as possible to what they were before.
