The rate of a reaction doubles or decreases by half when temperature changes by

The rate of evaporation of water doubles with every rise in temperature by

In general, it is observed that the rate of a chemical reaction doubles with every 10° rise in temperature. If this generalisation holds for a reaction in the temperature range 298 K to 308 K, what would be the value of activation energy for this reaction ? (R = 8.314 JK^(-1) mol^(-1) )

Arrhenius studies the effect of temperature on the rate of a reaction and postulted that rate constant varies with temperature exponentially as k=Ae^(E_(a)//RT) . Thuis method is generally used for finding the activation energy of a reaction. Keeping temperature constant, the effect of catalyst on the activation energy has also been studied. If the rate of reaction doubles for 10^(@)C rise of temperature form 290K to 300K, the activation energy of the reaction will be approximately :

The rate of reaction ........ with increase in temperature.

Calculate the activation energy of a reaction whose reaction rate at 300 K double for 10 K rise in temperature.
