Answer:

Solution:

For the reaction $2 BaO_{2} (s) ⇌ BaO (s) + O_{2} (g); Δ H = + ve$ In equillibrium $K_{P} = PO_{2}$ Hence, the value of equilibrium constant depends only upon partial pressure of $O_{2}$ . Further on increasing temperature formation of $O_{2}$ increases as this is an endothermic reaction. Hence, pressure of $O_{2}$ is dependent on temperature.
