SpletActivation energy is defined as the minimum amount of extra energy required by a reacting molecule to get converted into product. It can also be described as the minimum amount … SpletAs the temperature increases, the number of molecules having enough thermal thermal thermal energy to surmount the activation barrier increases. So the rate of the reaction increases. Under common circumstances, only a small fraction of the molecules have enough energy to make it over the activation barrier.
Spletactivation energy [ ăk′tə-vā ′shən ] The least amount of energy needed for a chemical reaction to take place. Some elements and compounds react together naturally just by being close to each other, and their activation energy is zero. Others will react together only after a certain amount of energy is added to them.
