The proton transfer reaction has been investigated in a flowing afterglow system independently in both directions at 297°K. The rate constants were found to be and . The ratio of rate constants, was found to be in agreement with the equilibrium constant, , determined from equilibrium concentrations. The value for K corresponds to a standard free energy change, . A calculated value for the standard entropy change, ΔS°298, of leads to a value for the standard enthalpy change, . Adoption of a recent photodetachment value for the electron affinity of NH2 leads to , and .
