Equilibrium constant decreases as the temperature

A. Increases, for an exothermic reaction

B. Decreases, for an exothermic reaction

C. Increases, for an endothermic reaction

D. None of these

Answer: Option A

Solution(By Examveda Team)

According to Le Chatelier's principle increase in temperature for an exothermic reaction will favor backward reaction and hence the product concentrations decreases and an new equilibrium is reached for an particular decrease in temperature and therefore the equilibrium constant decreases not increases.
