which statement best describes the use of a catalyst in a fuel cell?\nit reduces waste.\nit lowers energy requirements.\nit reduces toxic exhaust.\nit increases reaction rates.
Answer
Brief Explanations:
A catalyst is a substance that speeds up a chemical reaction by lowering the activation - energy barrier without being consumed in the reaction. In a fuel cell, its main function is to enhance the rate at which the electrochemical reactions occur. Reducing waste, lowering energy requirements, and reducing toxic exhaust are not the primary functions of a catalyst in a fuel cell.
Answer:
It increases reaction rates.
