Kinetic model of second order global

In this case, we have a reaction which is first order in respect to each component and presents global second order. We assume that the stoichiometric coefficients are also equal, which characterizes an elementary reaction. However, the coefficients can be different, as for example  

With respect to the component B, the reaction is first order (b = 1). Thus  

Substituting the expressions of the rates in Equation 5.3 for a continuous tubular system, we obtain the following solution (case (b))  

For a continuous stirred tank system, the solution will be different, because when substituting the rate (—r ) in Equation 4.10, we obtain  

Therefore, the choice of the reactor is very important in order to determine the kinetic parameters and use the specific kinetic expressions.
