On the validity of the steady-state approximation in non-isothermal kinetics. part III

The authors continue their considerations concerning the validity of the st eady-state approximation in non-isothermal kinetics. A sequence of two firs t-order consecutive reactions with an active intermediate was subjected to kinetic analysis by numerical solution of the corresponding differential ki netic equations for a number of particular cases. The results demonstrated that the rate of change of concentration of the active intermediate is negl igibly small if the assumption made in the isothermal case is also accepted for the non-isothermal case, i.e. k(2)(T(t))>>k(1)(T(t)).
