### Kw with increasing temperature in endothermic reaction

The autoprotolysis reaction is endothermic; do you expect Kw to increase or decrease with increasing temperature?

Since it’s endothermic, the reaction is absorbing heat so with increasing temperature, Kw would decrease? Is it the same idea as it is for K?

### Re: Kw with increasing temperature in endothermic reaction

Kw should increase with increasing temperature. Think of higher temperature as more heat available for the reaction. Since it is endothermic, heat goes on the reactant side. Apply Le Chatlier: more reactant pushes reaction to form more products. More products at equilibrium mean higher K value, hence higher Kw at higher temperature
