WitrynaRight, and because the rate law depends on CONCENTRATION of reactants (in this case H+), you have to determine which species produces more H+, HCl or HC2H3O2. Like you said, since HCl is a strong acid, you’ll get more disassociation and thus a larger concentration of H+ in solution. WitrynaMW of HCl= 36.5 g/mol. ∴ HCl gas is heavier than air. Upward displacement of air is good for gases that are heavier/denser than air, and are soluble in water. HCl is both heavier and denser than air. Thus, HCl is collected by upward displacement of air. Option C is correct.
