The Van’t Hoff equation shows how the equilibrium constant (K) of a chemical reaction changes with temperature.
In simple terms:
- It tells us whether increasing or decreasing temperature will favor the forward or backward reaction.
- For exothermic reactions, increasing temperature decreases K (less product formed).
- For endothermic reactions, increasing temperature increases K (more product formed).
In short: The Van’t Hoff equation connects temperature with the position of equilibrium, helping predict how equilibrium shifts with heat changes.
