NEETChemistryChemical EquilibriumMCQ+4 / −1
Reaction BaO2(g) ⇌\rightleftharpoons⇌ BaO(s) + O2(g); Δ\DeltaΔH = +ve. In equilibrium condition, pressure of O2 depends on
  1. A
    increase mass of BaO2
  2. B
    increase mass of BaO
  3. C
    increase temperature on equilibrium
  4. D
    increase mass of BaO2 and BaO both.

Correct answer: C

For the reaction

BaO2(g) ⇌\rightleftharpoons⇌ BaO(s) + O2(g); H = +ve.

At equilibrium Kp = PO2

[For solid and liquids concentration term is taken as unity]

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.
