The equilibrium constant (K(c)) for the ...

The equilibrium constant `(K_(c))` for the reaction HA + B `hArrBH^(+) + A^(-)` is 100. If the rate constant for the forward reaction is `10^(5)`, then constant for the backward reaction is

A

`10^(7)`

B

`10^(3)`

C

`10^(-3)`

D

`10^(-5)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K_(c) = (K_(f))/(K_(b))` `:.` `K_(b) = (K_(f))/(K_(c)) = (10^(5))/(100) = 10^(3)`
