Explain the effect of raising the temperature of exothermic equilibrium reaction.

Raising the temperature of an exothermic reaction will cause the equilibrium to move to the left, reducing the proportion of the product in the mixture. Exothermic reactions release heat and the reverse equilibrium reaction (endothermic) absorbs heat. Equilibrium reactions will always shift to reverse the change made to the conditions. Therefore in this example the equilibrium will move towards the left, to remove the additional heat added to the mixture.
