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.

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.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

yes
