The initial concentrations of A and B are same for `A +2B harr 3C` and when equilibrium concentrations of B and C are same then `K_(c)` is

A

0.25

B

0.75

C

0.5

D

1

Text Solution

Verified by Experts

The correct Answer is:
B

[B]=[C] `x=a // 5`
`K_(C)=([C]^(3))/([A][B]^(2))=(((3a)/(5))^(3))/((4a // 5)(3a // 5)^(2))=(3)/(4)`
