Chemical Kinetics

Rate constants of a reaction at \(500 \mathrm{~K}\) and \(700 \mathrm{~K}\) are \(0.04 \mathrm{~s}^{-1}\) and \(0.14 \mathrm{~s}^{-1}\), respectively; then, activation energy of the reaction is :

(Given: \(\log 3.5=0.5441, \mathrm{R}=8.31 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}\))
