For the reaction 2BaO2( s)⇌BaO(s)+O2( g);ΔH=+ve In equillibrium 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.
For the reaction BaO_2(s) ⇌ BaO(s)+ O_2(g) ; Δ H=+ ve . In an equilibrium condition, pressure of O_2 depends on:
