For the reaction BaO ₂(s) BaO (s)+ O ₂(g) ; H =+ ve . In an equilibrium condition, pressure of O ₂ depends on:
Options
- Aincreased mass of BaO ₂
- Bincreased mass of BaO
- Cincreased temperature at equilibrium
- Dincreased mass of both BaO ₂ and BaO
Correct answer
C. increased temperature at equilibrium
Step-by-step solution
For the reaction 2 BaO ₂( ~s ) BaO ( s )+ O ₂( ~g ) ; 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.
