Question

PLEASE HELP

Answer 1

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 $K.E = \frac{3}{2}kT$

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.

Answer 2

Answer:

a

Explanation:

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
