The Activation energy of a reaction whose reaction rate get doubles when the temperature rises from 10c to 60c is ? Please give the detailed answer?

Question

Answer

If rate of reaction increases then value of rate constant also increases.  From Arrhenius equation,  we can tell that if the value of k increases, then the value of e^(-Ea/RT) increases.  Then the value of  Ea/RT decreases.  So , value of activation energy decreases.
