Question

Which is the best explanation of how catalysts are used in chemical reactions A. Catalysts are needed for every chemical reaction to get started B. Each catalysts can only be used once for a given chemical reaction C. Catalysts lower the activation energy for chemical reactions to start D. Each catalysts can bind with a few different substrates to get chemical reaction stated faster

Answer 1

Answer:

A catalyst is a substance that can be added to a reaction to increase the reaction rate without getting consumed in the process. Catalysts typically speed up a reaction by reducing the activation energy or changing the reaction mechanism. Enzymes are proteins that act as catalysts in biochemical reactions

Explanation: I don't know if this will help but hopefully it does
