Derive an expression for the rate constant of first order reaction. The rate constant of first order reaction is `0.346" min"^(-1)`. What is the half-life?

Text Solution

Verified by Experts

Given that, rate constant, `k = 0.346" min"^(-1)`
As we know that, Half-life period, `t_(1//2) = (0.693)/( k)`
or, `t_(1//2) = (0.693)/( 0.346" min"^(-1) ) = 2" min"`
