What is the half-life period of a reaction having rate constant `6.93 xx 10^(-4)" s"`?

Text Solution

Verified by Experts

Unit of rate constant is `s^(-1)` so, it is a first order reaction and half-life `(t_(1//2) )` for first order is `= (0.693)/(k)`,
i.e. `t_(1//2) = (0.693)/(6.93 xx 10^(-4) ) = 0.1 xx 10^(4) = 10^(3)" s"`
