Question

Activation energy can be provided by the kinetic energy of moving molecules. true or false?

Answer 1

False

Step-by-step explanation:

Activation energy is simply the initial energy input which is needed to proceed a chemical reaction. The source of this energy is heat, which is obtained when reactant molecules absorb thermal energy from their surroundings. This thermal energy provides the kinetic energy of moving molecules, by speeding up the motion of the reactant molecules.

Therefore, the correct option is false.

Answer 2

In the concept of the chemical reactions, activation energy is the amount of energy that is to be available for the reaction to proceed. Likewise, this is the minimum energy that is to be available to start the reaction. This activation energy is most of the time supplied through heat. Only very small amount of the energy from the collisions of the reactants will produce the desired product. The collisions are the kinetic energy. Hence, the answer to this item is FALSE.
