The following equilibrium isothermal reaction (liquid phase) occurs in two similar (same volume) CSTR:AB
Reaction term in Damkholer number (Da) for above reaction can defined as (ka)(Cao). The reaction rate isra = (ka)(Ca) - (k-a)(Cb)
Equilibrium constant (Kc) is 1 and inital concentrations of A and B are Cao and zero (Cbo = 0), respectively. Da is equal 2 for each reactor in series configuration. What is the overall conversion of A for above equilibrium reaction?
1- if both reactors are in series?2- if both reactors are in parallel?
