Answer» Recall that catalysts are COMPOUNDS that accelerate the progress of a reaction without being CONSUMED. Common examples of catalysts INCLUDE acid catalysts and enzymes. Catalysts allow reactions to proceed faster through a lower-energy transition state. By lowering the energy of the transition state, which is the rate-limiting step, catalysts reduce the required energy of ACTIVATION to allow a reaction to proceed and, in the case of a reversible reaction, reach equilibrium more rapidly.CatalysisA catalyst SPEEDS up a reaction by lowering the activation energy required for the reaction to proceed.Explanation:D)Ea |
