Rate constant of a reaction with a virsu...

Rate constant of a reaction with a virsus is `3.1 xx 10^(-4) s^(-1)`. Time required for a virus to become `75%` inactivated is

A

` 35 min`

B

`70 min`

C

` 105 min`

D

` 17.5 min`

Text Solution

Verified by Experts

The correct Answer is:
B
` t_(1//2) = (0.693)/k = 2100s = 35 min`.
` t_(75%) = 2 t_(1//2) = 2 xx 35 = 70 min`.
