What will be the expression ofKpfor the given reaction if the total pressure inside the vessel is P and degree of dissociation of the reactant is a? The reaction

N 2 O 4 ⇄  2 NO 2

Options:

Answer:
B
Solution:

 Moles at t=0 Moles at equilibrium N2O411-a⇌2NO202a

Total moles at equilibrium=1-a+2a=1+a

P N 2 O 4 =( 1−a 1+a )P;  P NO 2 =( 2a 1+a )P

Kp=PNO2PN2O4=2a1+a2P21-a1+aP=4a2P1-a2
