Thus, whether a reaction “goes” or “does not go” can be used to determine the relative strength of the Bronsted acids and bases in the reaction. From the data below, determine the order of the strengths of the three Bronsted acids. Reaction 1: $NH_4^+ + (CH_3)_3N \rightarrow (CH_3)_3NH^+ + NH_3$ goes Reaction 2: $H_2TeO_3 + (CH_3)_3N \rightarrow (CH_3)_3NH^+ + HTeO_3^-$ goes Reaction 3: $NH_4^+ + HTeO_3^- \rightarrow H_2TeO_3 + NH_3$ does not go
