Question

Reaction BaO2 (s)$\rightleftharpoons$ BaO (s) + O2(g); ∆H = + ve. In equilibrium condition. The pressure of O2 depends on :

• A. Increase mass of BaO2
• B. Increase mass of BaO
• C. Increase temp. on Eqm.
• D. Increase mass of BaO2 and BaO both

Answer 1

Answer: (C)

Increase temp. on Eqm.

Answer 2

The correct option is (C) : Increase temp. on Eqm.

The following reaction is given: BaO2 (s)$\rightleftharpoons$BaO (s)+ O2 (g); H= +ive H is positive in this reaction because. Its nature is endothermic as a result. By using Le Chatelier's principle, we can show that the reaction moves ahead as the temperature rises. As a result, as the temperature rises at equilibrium, the pressure of oxygen will also rise.
