For the reaction 4NO(2)(g) +O(2)(g)hArr ...

For the reaction `4NO_(2)(g) +O_(2)(g)hArr 2N_(2)O_(5)(g)`, which of the following facts holds good ?

A

`K_(p)=K_(c)`

B

`K_(p)gt K_(c)`

C

`K_(p)ltK_(c)`

D

`K_(p)` and `K_(c)` cannot unless pressure of the system is provided.

Text Solution

Verified by Experts

The correct Answer is:
C
`Deltan lt 0 (i.e. -4-1+2=-3)`
so`K_(p) lt K_(c)`
as, `K_(p)=K_(c)(RT)^(Deltan)`
`Deltanlt0(-4-1+2=-3)`
