Simple reactions in series

Consider here the simplest irreversible and first-order reactions. If the reaction is consecutive or in series of the type  

The corresponding rates for each component in a system at constant volume are  

Considering that in the beginning of the reaction there is only pure reactant, we have  

Consequently, we can determine the time corresponding to this maximum, i.e. Inx 

Substituting Om x (Equation 6.11) into Equation 6.12, we finally obtain
