In which of the following reaction equilibrium, the value of equilibrium constant Kp will be more than is Kc ?
Correct answer: C. N2O4 ⇌ 2NO2
- A. 2HI ⇌ H2 + I2
- B. 2SO2 + O2 ⇌ 2SO3
- C. N2O4 ⇌ 2NO2
- D. None of these
Explanation
The relation Kp = Kc(RT)^Δn shows that Kp is greater than Kc for the textbook case Δn > 0. For N2O4 ⇌ 2NO2, Δn = 2 − 1 = +1, whereas reaction a has Δn = 0 and reaction c has Δn = −1.
