Answer:
Explanation:
A catalyst is a substance that increases the rate of a chemical reaction without itself getting consumed in the reaction as it helps in decreasing the activation energy. Thus, rate of reaction also increases.
A positive catalyst helps in increasing the rate of a chemical reaction whereas a negative catalyst decreases the rate of a chemical reaction.
Whereas when we increase the temperature then collisions between the particles increases due to increase in kinetic energy. Hence, rate of reaction increases with increase in temperature.
Thus, we can conclude that out of the given options adding a positive catalyst will increase the rate of a chemical reaction.

Bibliography- a separate list of books or texts referred to in the text read and can be consulted for more information and future use.
Appendix- a piece of text at the end of the book which is not connected to the main text
It means that someone is examining and explaining things that are the same and the things that are different between two similar things. It would be like taking two different kinds of flowers and noticing the differences in things like color, shape, etc, and also the similarities such as petals, stems, etc.
I hope this helps! :)
