The ratio Kp/Kc for the reaction: CO(g) + 1/2 O2(g) ⇌ CO2(g) is:
- (RT)^(1/2)
- RT
- 1
- 1/√RT
Correct answer: 1/√RT
Solution
The ratio Kp/Kc is determined by the equation Kp = Kc(RT)^(Δn), where Δn is the change in moles of gas. In this reaction, Δn is -1/2 (1 mole of CO2 produced from 1 mole of CO and 1/2 mole of O2), leading to Kp/Kc = (RT)^(-1/2) or 1/√RT.
