Respuesta :
Activation Energy. All chemical reactions, even exothermic reactions, need a certain amount of energy to get started. This energy is called activation energy. For example, activation energy is needed to start a car.
Answer:
The energy required to begin a reaction is known as activation energy. The most common form of activation energy is going to be heat.
Explanation:The energy required is called the activation energy. The minimum amount of energy needed to start a chemical reaction is given by the formula Ea=-RT*ln(k/A). R is the universal gas constant, T is temperature in Kelvin, k is the reaction rate coefficient and A is the frequency factor.
