(a) From the standpoint of favorable product distribution, order the contacting scheme, from most desirable to least desirable.
(b) For 90% conversion of A, find the concentration of R and S in the product stream. Equal volumetric rates of A and B are fed to an ideal PFR, and each stream has a concentration of 20 mol/L of reactant.

(a) What is the differential method of analysis of kinetic data?
(b) A first-order reversible liquid phase reaction A -> B is carried out in a CSTR at 427°C, with the initial concentration of A being equal to 2.0 mol/L.
