What conclusion is supported?
- A
Pure water at 50 C has pH > 7
- B
Kw is constant with T
- C
Autoionization is exothermic
- Dcheck_circle
Autoionization of water is endothermic
Explanation
Kw increases with temperature, indicating the autoionization 2 H2O <-> H3O+ + OH- is endothermic (Le Chatelier).
