Design Equation for First-Order Reversible Reaction

3 Design Equation for First-Order Reversible Reaction 

Consider a reversible first-order reaction A B, carried out in a constant-volume isother- 

Rearranging Equations 3.19 and 3.22, we obtain expressions for calculafing conversion Xy for a specified value of space fime x  

Design equafions derived for an ideal CSTR and an ideal PER for some fypical reactions are summarised in Table 3.1. 

If the space time required to achieve 80% conversion in an ideal PFR is 10 min, what is the space time required to achieve the same conversion in an ideal CSTR The reaction is second-order irreversible. The feed concentration of the reactant is 4 kmol/m. What are the conversions in the PFR and the CSTR if space time is doubled
