Equilibrium - Result Question 7

####8. In which of the following equilibrium Kc and Kp are not equal?

[2010]

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

(b) SO2(g)+NO2(g)SO3(g)+NO(g)

(c) H2(g)+I2(g)2HI(g)

(d) 2C(s)+O2(g)2CO2(g)

Show Answer

Solution:

  1. (d) 2C( s )+O2(g)2CO2(g)

Δn=21=+1

Kc and Kp are not equal.

If Δn=0, then (RT)Δn=1

Kc=Kp
