- Why does the dehydration of an alcohol more often use concentrated sulfuric acid, H2SO4H2SO4, as the acid catalyst rather than dilute hydrochloric acid, HCl? Select one or more: Hydrochloric acid is too small to effectively react with the alcohol in the reaction. The additional water solvent from a dilute solution could reverse the dehydration reaction. Only acids with more than one proton can complete the dehydration reaction. The presence of the chloride ion could result in a competing substitution reaction.arrow_forwardHNO, (1 eq.)

Zn(s) 2HCI(aq)ZnCl2(aq) + H2(g) Zinc + Hydrochloric Acid Zinc Chloride + Hydrogen What causes the reaction to proceed faster with concentrated acid? The concentrated hydrochloric acid causes more hydrogen gas to be produced. The pressure of hydrogen gas molecules increases as concentration increases. The concentrated hydrochloric acid molecules move faster than in dilute acid. There are more collisions between the zinc and concentrated hydrochloric acid.
