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.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
