Chemistry and Chemical Reactivity

Equal amounts of two acids- -HCl and HCO $_{2} \mathrm{H}$ (formic acid)-are placed in aqueous solution. When equilibrium has been achieved, the HCl solution has a much greater electrical conductivity than the HCO $_{2} \mathrm{H}$ solution. Which reaction is more product-favored at equilibrium?
$\mathrm{HCl}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\ell) & \rightleftarrows \mathrm{H}_{3} \mathrm{O}^{+}(\mathrm{aq})+\mathrm{Cl}^{-}(\mathrm{aq}) \\\mathrm{HCO}_{2} \mathrm{H}(\mathrm{aq})+\mathrm{H}_{2} \mathrm{O}(\ell) & \rightleftarrows \mathrm{H}_{3} \mathrm{O}^{+ (\mathrm{aq})+\mathrm{HCO}_{2}^{-}(\mathrm{aq})$
