Chemistry - Chemical Kinetics Question with Solution | TestHub

For a first order reaction$\mathrm{A}\to \mathrm{B}$, the rate constant,$\mathrm{k}=5.5\times {10}^{-14}{ \mathrm{s}}^{-1}$. The time required for$67\%$completion of reaction is$\mathrm{x}\times {10}^{-1}$times the half life of reaction. The value of$\mathrm{x}$is Nearest integer) (Given :$\log 3=0.4771$)
