Question:- What is the name of the substance that speeds up a reaction?

Answer: Catalyst is a substance that participates in a chemical reaction and helps to achieve the percentage which it is not changed or consumed during the process. Catalysts are known to help out in this by offering an easier route through which the reactants can overcome the energy barrier since it requires lesser energy as compared to the initially proposed route of reacting. They stabilize the reactants and transition state allowing the breaking and reforming of chemical bonds all in order to increase the rate of the reaction. Catalysts come in all types; there are homogeneous catalysis and heterogeneous catalysis, and they are used in chemical manufacturing, petroleum refining, car catalytic converters, etc. They are also found to be involved significantly in various biological activities and enzymes are those which really work as catalyst in the living forms. Heterogeneous catalysts can be in a different phase from the reactants while homogeneous ones are in the same phase as the reactants theirs advantages make them useful in industrial processes majors are they can be reused after the reaction.
