The van’t Hoff equation ln K 2 K 1 = + Δ r H o R 1 T 1 1 T 2 = + Δ r H o R T 2 T 1 T 1 T 2 (By knowing the equilibrium constant of a reaction at T 1 we can calculate the equilibrium constant of a reaction at T 2 )

Assume T 2 > T 1 For endothermic reaction Δ r H>0, then K 2 > K 1 For exothermic reaction Δ r H<0, then K 1 > K 2 • Increase of T shifts the equilibrium toward products in an
