See lessWe can decrease the activity of an oxide by 1) Increasing the partial pressure of Oxygen in the reaction. 2) Reacting it with other metal which has more stable oxide so that reaction goes in forward direction. You can write the equilibrium constant equations for the reaction and analyse the same.
