Calculate rate constant for the first order reaction, whose half-life period is 4.6 s.

Explanation

We are given that
Half life ` t _(1//2) = 4. 6 s `
We are to calculate the rate constant for first order reaction.
Using the formula, `t _(1//2) = ( 0. 693)/( k ) therefore k = ( 0. 693)/t _(1//2) = ( 0. 693)/( 4. 6) = 0. 107`
