Question

Consider the following equation in a closed container:

N₂O₄(g)⇄2NO₂(g)

At a fixed temprature, the volume of the reaction container is halved.For this change,Which of the following statements, holds true regarding the equilibrium constant (K_p) and degree of dissociation(α)

Answer 1

Correct option (D)KP does not change, but α changes

Explanation:

For the equilibria: N₂O₄(g) ⟺ 2NO₂(g) KP = KC x (RT)^Δn Since temperature is constant so Kc or KP will remain constant. Further since volume ishalved, the pressure will be doubled so α will decrease so as to maintain the constancy of KC or KP.
