Adding a catalyst to a chemical reaction results in
(1) a decrease in activation energy and a decrease in the reaction rate
(2) a decrease in activation energy and an increase in the reaction rate
(3) an increase in activation energy and a decrease in the reaction rate
(4) an increase in activation energy


Sagot :

Adding a catalyst to a chemical reaction results in a decrease in activation energy and an increase in the reaction rate.

Answer: Option (2) is the correct answer.

Explanation:

Activation energy is the minimum amount of energy required to start or initiate a chemical reaction.

Whereas a catalyst helps in increasing the energy of reactant molecules so that they can overcome activation energy barrier and actively participate in the reaction.

Hence, adding a catalyst to a chemical reaction results in a decrease in activation energy and an increase in the reaction rate.
