Effect of Temperature Change
The shift in equilibrium caused by heating or cooling, which uniquely also changes the equilibrium constant.
Formula / equation
exothermic: K falls as T rises
Unit
K
In depth
Heat can be treated as a product of an exothermic reaction and a reactant of an endothermic one, so raising temperature favours the endothermic direction. Temperature is the only variable that changes K, because it alters the underlying free energy balance.
Examples in the real world
Ammonia yield falls as the Haber reactor is heated, forcing a compromise between yield and rate.
