Why is reaching activation energy necessary?
a)reactants require a minimum amount of energy to start to break a chemical bond. b)products require a minimum amount of energy to start to break a chemical bond. c)reactants must have the maximum amount of energy to start to break a chemical bond.
d) products must have the maximum amount of energy to start to break a chemical bond.

Answer;

A) Reactants require a minimum amount of energy to start to break a chemical bond.

Explanation;

-Activation energy is the minimum amount of energy that reactants must absorb before a chemical reaction will start. It is also referred to as free energy of activation.

-Activation energy is required to activate atoms or molecules of the reactants to a state that they can undergo chemical transformation to form products.
