Answer 2

Explanation:

K2O will not split into Potassium and Oxygen at 300C, but when heated in an inert atmosphere will disproportionate as the Oxide becomes less favourable compared to the Superoxide and elemental Potassium. At temperatures of greater than 300C, the Oxide ion is capable of reducing the Potassium ion
