The amount of energy needed for a reaction to occur is called?

a
potential energy
b
start up energy
c
activation energy
d
kinetic energy

c

activation energy

The correct answer is:

c) activation energy

Activation energy is the amount of energy needed for a chemical reaction to occur. It is the energy required to break the existing chemical bonds in the reactants and initiate the formation of new bonds in the products.

The correct answer is c) activation energy. The activation energy is the amount of energy required to initiate a chemical reaction. It represents the energy barrier that reactant molecules must overcome in order to successfully form products. To find the answer to this question, you need to have some background knowledge about the concept of activation energy and its role in chemical reactions.
