Substance X is converted to substance Y in a chemical reaction. What role would a catalyst play in this scenario?






A.
It would increase the solubility of substance X into the solvent needed to speed up the reaction.




B.
It would speed up the reaction by becoming part of the products.




C.
It would increase the pH in order to dissolve substance X to make the reaction happen.




D.
It would speed up the reaction without changing or becoming part of the product

D. It would speed up the reaction without changing or becoming part of the product.

A catalyst is a substance that is used to speed up a chemical reaction. It does this by providing an alternative reaction pathway with a lower activation energy, which is the energy required for the reaction to occur. The catalyst itself is not consumed in the reaction and does not become a part of the products. Instead, it helps to facilitate the reaction by reducing the energy barrier for the reaction to proceed. This allows the reaction to occur at a faster rate, without being permanently altered or consumed in the process.
