Solve this: Q.58. In a 0.25 L tube dissociation of 4 mol of NO is take place. If its degree of dissociation is 10 %. The value of K P for reaction 2 N O ⇌ N 2 + O 2 is :- (1) 1 18 2 (2) 1 8 2 (3) 1 16 (4) 1 32 Share with your friends Share 8 Vartika Jain answered this Dear Student, NO ↔ 12N2 + 12O2Initial 40.25 0 0 At equil. 40.25(1-α) 4α2×0.25 4α2×0.25 Kc = [O2]12[N2]12 [NO]It is given that, α = 0.10So, [O2]=[N2] = 4×0.102×0.25=45 [NO]=40.25(1-0.10) =4×0.900.25=725 So, Kc =(45)12(45)12(725)=472=118Now, Kp = Kc(RT)∆nFor the given reaction, ∆n=0So, Kp=Kc =118There seems to be some problem in the options given, it should be A but instead of (18)2 it should be 18. -2 View Full Answer
