Development of model for a first order reversible

5 Development of a rate model for a first order reversible reaction 

For isothermal conditions and absence of external (liquid-solid) mass transfer resistance the diffusion reaction model for reactions within the porous ion exchange catalyst particles can be written as (Ramachandran and Chaudhari, 1983) 

The overall rate of reaction of acetic acid (reactant A) can be described as 

The solution of O, the Thiele parameter was obtained following the Bischoff s approximation (1965). Accordingly ([) in this case is given by
