For the reaction CO(g) + Cl2(g) ⇌ COCl2(g) the Kp/Kc is equal to

1. √RT
2. RT
3. 1/RT
4. 1.0

Correct answer: 1/RT

Solution

The relationship between Kp and Kc is given by the equation Kp = Kc(RT)^(Δn), where Δn is the change in the number of moles of gas. In this reaction, Δn is negative, leading to Kp being equal to Kc divided by RT, hence Kp/Kc equals 1/RT.
