chemical energy transition state chemical reaction activation energy temperature

pairs
a measure of the average kinetic
energy of particles

energy that a substance has because
of the arrangement of its atoms

the process of breaking down an
existing set of substances to
form a new set of substances

a phase in a reaction in which
existing bonds break to form

Explanation:

Temperature quantifies average particle kinetic energy. Chemical energy is stored in atomic arrangements. A chemical reaction involves forming new substances from existing ones. Transition state is the high-energy intermediate with breaking/forming bonds. Activation energy is the energy needed to start a reaction.

Answer:

temperature - a measure of the average kinetic energy of particles, chemical energy - energy that a substance has because of the arrangement of its atoms, chemical reaction - the process of breaking down an existing set of substances to form a new set of substances, transition state - a phase in a reaction in which existing bonds break to form new ones, activation energy - the minimum energy required to initiate a chemical reaction
