The energy level necessary to enable a reaction to occur is called energy. 1.)activation 2.)kinetic 3.)potential 4.)nuclear

The correct answer is activation.

Activation energy is the minimum energy required by the reactant species to start a chemical reaction.

Kinetic energy is the energy possessed by an object by virtue of its motion.

Potential energy is possessed by an object when it is a rest.

Nuclear energy is the energy released during the process of nuclear fission or nuclear fusion.
