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

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

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.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
