Question

What is activation energy?

A.
energy required by the substrate to fit into the active site

B.
energy supplied by enzymes in a chemical reaction

C.
energy released when reactants combine to become products

D.
energy required to break the chemical bonds of the reactants

Answer 1

the energy required to break the chemical bond of the reactants

Answer 2

Activation energy is the energy required to break the chemical bonds of the reactants in a chemical reaction.

Step-by-step explanation:

The correct answer is D. Activation energy is the energy required to break the chemical bonds of the reactants in a chemical reaction. It is the minimum amount of energy needed for a reaction to occur. Activation energy acts as a barrier that the reactant molecules must overcome to undergo a reaction and form products. For example, when wood is burned in a fire, activation energy is needed to break the bonds between the carbon and hydrogen atoms in the wood and allow them to react with oxygen to produce carbon dioxide and water vapor.
