Equilibrium - Result Question 15

####16. K1 and K2 are equilibrium constant for reactions (i) and (ii)

N2(g)+O2(g)2NO(g)

NO(g)12N2(g)+12O2(g)

Then,

[1989, 94, 2005]

(a) K1=(1K2)2

(b) K1=K22

(c) K1=1K2

(d) K1=(K2)0

Show Answer

Solution:

  1. (a) For reaction (i)

KP=PCO2PCH4×[PO2]2

K1[NO]2[N2][O2]

and for reaction (ii)

K2[N2]1/2[O2]1/2[NO] therefore K1=1K22
