For the dissociation reaction N2O4(g) ⇌ 2NO2(g), the degree of dissociation ( α ) in terms of Kp and total equilibrium pressure P is:- (1) α = 4 P + K p K p (2) α = K p 4 P + K p (3) α = K p 4 P (4) α = K p 2 P Share with your friends Share 16 Mohan Kumar answered this Dear Student, Regards -42 View Full Answer
