The half-life period of a reaction of first order is 100 s. Calculate its rate constant.

Text Solution

Verified by Experts

we know for a first order reaction,
`t_(1//2) = (0.693)/( k)` or `k = (0.693)/(t_(1//2))`
Now, `t_(1//2) = 100" s"`.
`therefore k = ( 0.693)/( 100 s) = 6.93 xx 10^(-3)" s"^(-1)`
