Effect of Temperature on Rate of reaction |Temperature Coefficient

What is the effect of temperature on the rate of a reaction.

What is the effect of temperature on the rate of reaction ? Explain giving reasons.

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 :
