Which of the following is (are) not correct for a first order reaction?

A

`t_(1//2) prop a`

B

`t_(1//2) prop 1//a`

C

`t_(1//2) prop a^(0)`

D

`t_(1//2) prop a^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A, B, D

For first order reaction,`t_(1//2) = (0.693)/(k)`, i.e., `t_(1//2)` is independent oof concentration.
