Chemical Kinetics And Nuclear Chemistry

The rate of First order reaction is \(0.04 \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\) at 10 minutes and \(0.03 \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}\) at 20 minutes after initiation. Half life of the reaction is _______ minutes.

(Given \(\log 2=0.3010, \log 3=0.4771\))
