Problem

Two possible proton-transfer equations between acetic acid and hydrogencarbonate ion are proposed: (I)

CH_3COOH + HCO_3^- \rightarrow CH_3COO^- + H_2CO_3

(II)

CH_3COOH + HCO_3^- \rightarrow CH_3COOH_2^+ + CO_3^{2-}

Indicate which equation is more likely to occur to the greater extent in aqueous solution and justify your choice in one sentence.
