Kinetics properties of the reaction N~+(~3P)+H_2→NH~++H

The kinetic properties of N+ + H2 →NH+ + H reaction have been studied theoretically.It is found that this reaction is an endothermic reaction and cannot react forward spontaneously under low temperature.The kinetic properties of reactions are calculated using three methods at a pressure of 1 mbar and a temperature ranging from 1 to 2000 K.It is found that this reaction has very low reaction rates under low temperature,and the rate decrease drastically fast with decreasing temperature.The results are compared with various experiments.An analysis of the free energy of activation of this reaction dependence of the hydrogen reactant rotational energy yields an assumption that the hydrogen reactant rotational energy does not affect the reaction rate coefficient under low temperature.
