WebArrhenius rate parameters are required for both the high- and low-pressure limits. The rate coefficients for these two limits are then blended to produce a smooth pressure-dependent rate expression. ) and the low-pressure limit ( ) are as follows: (7.1-15) (7.1-16) The net rate constant at any pressure is then taken to be (7.1-17) where ground stop ffa
