Ion-molecule reactions of formic acid. I. Proton-transfer reactions

Abstract

Rate coefficients are reported for a number of proton-transfer reactions with formic acid. These reactions can be represented by the general equation

                           XH⁺+HCOOH → (HCOOH)H⁺ +X

: (X = CH₄, H₂O, N₂, CO, HCN, HCHO, CH₃OH and H₂S). Reasonable agreement was obtained between our observed results and predictions based on the average-dipole-orientation (ADO) model except that ADO theory may slightly underestimate the collision rate.
