Low-Pressure Reaction Kinetics

When treating the kinetics of hydrogen combustion consider first a reaction at low pressure under isothermal conditions at its initial stage (see [230]). 

At 800 K, OH and O can be considered to be the more active centers (compared to H). Thus, using the method of partial steady-state concentrations, it can be assumed that d[OH]/dt = 0 and d[0]/dt = 0. Then, the above three equations approximately reduce to 

The conditions permitting formal reduction of the problem of several active centers to a one-center problem have been analysed in detail [15, 412].
