In an equilibrium `A+BhArrC+D,A` and B are mixed in a vessel at temperature T. The initial concentration of A was twice the initial concentration of B. After the attainment of equilibrium, concentration of C was thrice concentration of B, calculate `K_(c)`.

A

`K_c=1.8`

B

`[A]_(eqn)=[d]_(eqn) xx 1.66`

C

`K_c=2.8`

D

`[A]_(eqn) = [C]_(eqn) xx 2.5`

Text Solution

Verified by Experts

The correct Answer is:
A, B

given `[c]_(eqn)=3[B]_(eqn)`
`x=3(a-x), x=(3a)/(4)`
`[A]_(eqn)=(5a)/(4), [B]_(eqn)=(a)/(4), [C]_(eqn)=(3a)/(4), [D]_(eqn)=(3a)/(4)`
