Rate constant of a first order reaction ...

Rate constant of a first order reaction A products is `0.016 min^(-1)`. Calculate the time required for 80% of the reaction to be completed.

Text Solution

Verified by Experts

`K = (2.303)/(t) log.(a)/(a-x)`
`t = (2.303)/(0.016)log.(100)/(100-80)`
`t = (2.303)/(0.016)log 5`
`t = 100.6 min`
