Following equilibrium is established at temperature T.
A(g) `hArr` B(g) + C(g)
If equilibrium concentrations of A, B and C are 1M, 2M and 2M respectively,`K_​p`​ for the reaction is :-

A

RT

B

2RT

C

4RT

D

5.4RT

Text Solution

Verified by Experts

The correct Answer is:
C
`K_C="[B][C]"/"[A]"`
`(2xx2)/1`
`=(2xx2)/1` =4M`
`K_P=K_C(RT)`
`K_P` = 4RT
