What is difference between catalyst and reagent |
| Answer» A\xa0reagent\xa0is a substance or compound added to a system to cause a chemical reaction, or added to test if a reaction occurs.\xa0The terms\xa0reactant\xa0and\xa0reagent\xa0are often used interchangeably—however, a\xa0reactant\xa0is more specifically a substance consumed in the course of a chemical reaction.\xa0Solvents, though involved in the reaction, are usually not called reactants. Similarly,\xa0catalysts\xa0are not consumed by the reaction, so they are not reactants. In\xa0biochemistry, especially in connection with\xa0enzyme-catalyzed reactions, the reactants are commonly called\xa0substrates. | |
