Effect of Temperature on Equilibrium ( Dr. Bülent BELİBAĞLI )

 

3. Effect of Temperature on Equilibrium

The equilibrium constant is temperature dependent.

• For an endothermic reaction, DH > 0 and heat can be considered as a reactant.

• For an exothermic reaction, DH < 0 and heat can be considered as a product.

a. Raising the temperature of an equilibrium mixture shifts the equilibrium condition in the direction of the endothermic reaction.

b. Lowering the temperature of an equilibrium mixture shifts the equilibrium condition in the direction of the exothermic reaction.
