The rate constant of a reaction with a virus is `3.3xx10^(-4)S^(-1)`. Time required for the virus to become `75%` inactivated is

A

`35 mi n`

B

`70 mi n`

C

`105 mi n`

D

`17.5 mi n`

Text Solution

Verified by Experts

The correct Answer is:
B
`t_(1//2)=(0.693)/(k)=2100s=35 min`
`t_(75%)=2t_(1//2)=2xx35=70 min`
