The answer is Cl- or A. Hope it helps

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.

Adding a catalyst to a chemical reaction results in a decrease in activation energy and an increase in the reaction rate, as catalysts speed up chemical reactions by lowering the required activation energy. The correct answer to the given question is option (2) a decrease in activation energy and an increase in the reaction rate

In the world of Chemistry, a catalyst is a substance that increases the speed of a chemical reaction without itself undergoing any permanent chemical change. It achieves this acceleration by lowering the activation energy required for the reaction to occur. Therefore, adding a catalyst to a chemical reaction results in a decrease in activation energy and an increase in the reaction rate (option 2).

The activation energy is the minimum amount o f energy required for a chemical reaction to proceed. By lowering this energy barrier, a catalyst allows the reaction to proceed more quickly, in other words, it increases the rate of the reaction.

The correct answer to the given question is option (2) a decrease in activation energy and an increase in the reaction rate

Answer:

Label

Explanation:

You need to search if the chemical need a glass or plastic container. Also if the chemical need to be in a clear or dark container that can protect it from light. Also if need to be a certain temperature, for example, if need to be in the fridge or can be at room temperature.

Most important is that you need to label with the name, formula, date, and if you have the number of lot and the expiration date.
