The rate equation for the reaction `2A+B rarr C` is found to be: `rate = k[A][B]`. The correct statement in relation of this reaction is thatA. The value of `k` is indepedennt of the initial concentration of `A` and `B`.B. `t_(1//2)` is a constant.C. The rate of formation of `C` is twice the rate of disappearnce of `A`.D. The unit of `k` must be `s^(-1)`

Answer» Correct Answer - A
For second order reaction,
(a) Correct statement.
(b) `t_(1//2) prop (a)^(-1)`
( c) `(d[C])/(dt) = (-d[A])/(2 dt)`
(d) For second order, units of `k` is `L mol^(-1) s^(-1)`.
