The rate constant for the reaction of O2+ with N2 to produce NO+ plus NO has been measured at 423, 523, and 623 K in a turbulent ion flow tube. Much improved upper limits for this reaction at the three temperatures are 2, 4, and 10x10(-21) cm3 s-1, respectively. These results should render this reaction irrelevant when modeling all plasmas involving atmospheric gases.
