In which of the following equilibrium `K_c` and `K_p` are not equal ?

A

`H_2(g) + I_2(g) hArr 2HI(g)`

B

`2C(s)+O_2(g) hArr 2CO(g)`

C

`2NO(g) hArr N(g)+O_2(g)`

D

`SO_2(g) +NO_2(g) hArr SO_3(g) + NO(g)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K_p=K_c(RT)^(Deltan_g)`
`2C(s)+O_2(g) hArr 2CO(g)`
`Deltan_g` =2-1=1 for the reaction
Thus `K_p ne K_c`
When `Deltan_g`=0, `K_p=K_c` is options (a),(c) ,(d)
