Pure ammonia is placed in a vessel at a temperature where its degree of dissociation (α) is appreciable. At equilibrium :
Consider the following equilibrium in a closed container:
N2O4 (g) ⇋ 2NO2 (g)
At a fixed temperature, the volume of the reaction container is halved. For this change, which of the following statements holds true regarding the equilibrium constant Kp and degree of dissociation α?
