In a system `P_(s) hArr 2Q_(g) + R_(g)`, at equilibrium is concentration of R 'Q' is doubled than how many times the concentration of R at equilibrium will be :-

A

Double of its original concentration

B

`(1)/(4)` of its orignal concentration

C

`(1)/(2) `of its original concentration

D

4 times of its orignal concentration

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(C)=[CI]^(2)[R]` ....(1)
`K_(C)=4[CI]^(2)[R]^(1)` ....(2)
(1),(2) `[R]^(1)=(1)/(4)[R]`
