Activation energy of a chemical reaction can be determined by ……..

Activation energy of a chemical reaction is related to rate constant of a reaction at two different temperatures , i.e. k1and k2 respectively , In k1k2=EaR1T1−1T2where, Eα = activation energy, T2 = higher temperature T1 = lower temperature, k1= rate constant at temperature (T1) k2 = rate constant at temperature T2This equation is known as Arrhenius equation.
