Assertion : For a first order reaction,t...

Assertion : For a first order reaction,`t_(1//2)` is indepent of rate constant.
Reason : For a first reaction `t_(1//2) prop [R]_(0)`.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
for a first order reaction half-life period is constant i.e., it is independent of initial concentration of the reacting species. It is related to rate constant as `t_(1//2) = (0.693)/(k)`
