If K(1),K(2),K(3) are equilibrium consta...

If `K_(1),K_(2),K_(3)` are equilibrium constant for formation of `AD,AD_(2),AD_(3)` respectively as follows `A+DhArrD,AD+DhArrAD_(2),AD_(2)+DhArrAD_(3)`. Then equilibrium constant `'K' "for" A+3DhArrAD_(3)` is related as

A

`K_(1)+ K _(2)+ K_(3)=K`

B

`log K_(1) +log K_(2) + log K_(3) =log K`

C

`K_(1) +K_(2) =K_(3)+K`

D

`log K_(1) +log K_(2)=log K_(3) + log K`

Text Solution

Verified by Experts

The correct Answer is:
B
`A+D hArr AD, K _(1)……..(1)`
`AD+ D hArr AD_(2), K_(2)…….(2)`
`AD_(2) +D hArr AD_(3), K_(3)………(3)`
`A+D_(3) hArr AD_(3), K………(4)`
`(4) =(1) +(2) +(3)`
`K =KI_(1) xxK_(2) xxK_(3)`
`log K =log K _(1)+ log K_(2)+log K _(3)`
