Question

Which is the best definition of activation energy?

O the energy required to end a chemical reaction
O the energy required to bind a substrate to an active site
• the energy required to form or break the bonds of reactant molecules
• the energy required to re-form bonds in product moleculesp

Answer 1

Step-by-step explanation:

The best definition of activation energy is: the energy required to form or break the bonds of reactant molecules. Activation energy is the minimum amount of energy required for a chemical reaction to occur by breaking the bonds of reactant molecules, enabling them to react and form product molecules. The activation energy is determined by the energy difference between the reactants and the activated complex (a high-energy intermediate state), and it affects the rate of the chemical reaction.
