A first order reaction is 50% completed ...

A first order reaction is `50%` completed in `1.26 xx 10^(14)`s. How much time would it take for `100%` completion?

A

`1.26 xx 10^(15) s`

B

`2.52 xx 10^(14) s`

C

`2.52 xx 10^(28) s`

D

Infinite

Text Solution

Verified by Experts

The correct Answer is:
D

Reaction would be 100% complete only after infinite time which cannot be calculated.
