Question

Reactant A in a liquid either isomerizes or dimerizes

A → R (desired) , r_R = k₁ C_A

A + A → S (unwanted), r_S = k₂ C_A²

a) write j(R/A) and j[R/(R+S)]

b) If in batch reactor, C_A0 =1 mol/L. When reaction is completed (i.e. C_A =0), C_S = 0.18mol/L in resultant mixture, what is the ratio of rate constants – k₁/k₂ ?

c) Find C_Rf when XA=80% in PFR

d) Find C_Rf when XA=80% in MFR
