If a particular process is endothermic, the reverse process must be a (an) chemical change. exothermic process. endothermic process. isothermal process. none of the above

If a particular process is endothermic, the reverse process must be an

exothermic process. This is because, when the endothermic process

occurs, the substance takes energy from its surroundings. The reverse

of this reaction would be for the substance to release energy into its

surrounding. Therefore, the answer is exothermic.
