PLEASE HELP
Tori is studying a chemical reaction and its reaction rate after observing the initial rate she adds thermal energy to the reaction. Which of the answer choices correctly describes how the addition of thermal energy will affect the reaction rate ?

A.) increase in energy will cause the reactance particles to move faster which will increase their temperature and lead to a faster reaction rate

B.) increase in energy will cause the reactants particles to move faster which will increase their temperature and lead to a slower reaction rate

C.) The increasing energy will cause the reactance particles to move faster which will decrease their temperature and lead to a faster reaction rate

D.) The increasing energy will cause the reactance particles to move slower which will decrease their temperature and lead to a slower reaction rate

E.) increase in energy will cause the reactants particles to move slower which will decrease their temperature and lead to a faster reaction rate

because when particles are in a solid and you heat it up they start to move rapidly creating energy and heat causing the solid to turn into a liquid or a gas. this is called

gas= evaporation

liquid = melting

hope this helps

Answer: Option (A) is the correct answer.

Explanation:

Since, thermal energy is being added to the chemical reaction which will lead to an increase in the motion of molecules.

Hence, kinetic energy of the molecules will increase. As a result, number of collisions within the molecules will increase leading to an increase in the rate of reaction.

Also, it is known that [tex]K.E = \frac{3}{2}kT[/tex]

Therefore, we can conclude that the statement increase in energy will cause the reactance particles to move faster which will increase their temperature and lead to a faster reaction rate correctly describes how the addition of thermal energy will affect the reaction rate.
