For the reaction, `A iff n B` the concentration of A decreases from 0.06 to 0.03 mol `L^(-1)` and that of B rises from 0 to 0.06 mol `L^(-1)` at equilibrium. The values of n and the equilibrium constant for the reaction, respectively, are

A

2 and `0.12`

B

2 and `1.2`

C

3 and `0.12`

D

3 and `1.2

Text Solution

Verified by Experts

The correct Answer is:
A
`{:(A, hArr , nB),(t=0, 0.06, 0), (t=t, 0.03, 0.06):}`
`alpha c=0.03`
`n alpha c=0.06`
`n=2`
`k_(c)=([B]^(n))/([A])=((0.06)^(2))/(0.03)=0.12`
