Dayanara Schmidt · Answer 1

T he energy required to break the bonds of reactant molecules

When a chemical reaction takes place, chemical bonds between the reactants must be broken in order for the bonds between product molecules to form. Activation energy is the energy required to break these bonds, and it causes the chemical reaction to start.

Victoria Harding · Answer 2

Activation energy is the energy required to break the bonds of reactant molecules. It is the minimum energy required to start off a chemical reaction.
