In a chemical reaction, activation energy increases the of the reactants. this outcome causes the particles to collide, which results in the of new products.
first blank-
a-amount of chemical energy
b- number of particles
c- temperature
second blank-
a- breaking up
b-formation
c-reactions

The answer is;

first blank-

A

Second blank-

B

Activation energy raised the potential energy of reactants to begin a chemical reaction. This requires an initial input of energy into the reaction before the reaction can then proceed spontaneously. That delta G of the activation energy is usually positive. This activation energy destabilized the stable  bonds of the reactants so they can form new bonds. This results to a transition state that is a high-energy state.

the device is called “ rocket engine”
