Respuesta :
The activation energy is the bare minimum of energy required for compounds to undergo a chemical reaction in physics and chemistry.
The rate constant of a reaction at various temperatures can be used to calculate the activation energy. from Arrhenius Law With two known temperatures and a rate constant for each temperature, the activation energy can also be determined directly. If the rate constant is known, we can use the Arrhenius equation to get the activation energies, and vice versa. A chemical reaction's activation energy can be calculated by comparing rate constants between two temperatures. The Arrhenius equation can be used to determine it. The bare minimum additional energy needed by a reactive molecule to transform into a product is known as activation energy.
