Correct answer: (c) temperature of equilibrium
Explanation:
For the reaction
2BaO2(s) ⇌ 2BaO(s) + O2(g); ΔH = +ve.
At equilibrium KP = PO2
Hence, the value of equilibrium constant depends only upon partial pressure of O2. Further on increasing temperature formation of O2 increases as this is an endothermic reaction. Hence, pressure of O2 is dependent on temperature.
