Langmuir-Hinshelwood Kinetics and Intraparticle Temperature Gradients

15 Langmuir-Hinshelwood Kinetics and Intraparticle Temperature Gradients 

By combining the Equations 7.14 and 7.3S it can be seen that, for this case, Ant is given by 

Assuming that heat effects are negligible if 5C, is smaller than 10 %, the criterion for isothermal operation becomes 

From the discussion about simple reactions it is readily seen that a general criterion for isothermal operation in the high t] region is  

Since all conclusions drawn for simple reactions also hold for bimolecular reactions, the general criterion for bimolecular reactions becomes
