Question

Which of the following is true about catalysts?

Catalysts increase the number of collisions that occur between reactants.
Catalysts increase the activation energy by forming new reactants.
Catalysts reduce the potential energy of the compounds that are produced.
Catalysts reduce the energy needed for the reaction to take place.

Answer 1

The answer is D. catalysts reduce the energy needed for the reaction to take place.

Step-by-step explanation:

Answer 2

The correct answer is that the catalysts enhances the collisions numbers that take place between the reactants.

Explanation:

A component that assists in elevating the rate of a chemical reaction without itself getting spent is known as a catalyst. A catalyst generally reduces the activation energy so that the molecules comprising low energy can take part in the process. As a consequence, there takes place more amount of collisions amongst the molecules. Thus, the rate of reaction will enhance because of which the production of products will become quicker. Thus, it can be concluded that the catalysts enhances the collisions taking place between the reactants.
