Just solve question C.

1) Consider the reaction 2A B in an isothermal CSTR. Let F; be the inlet volumetric flow rate, Cai the inlet reactant concentration, V the varying reactor volume, Ca the reactant concentration in the reactor, and F the outlet flow rate which is manipulated. Assume that the density p is constant and that the reactor was initially filled with the feed stream. Let the kinetic rate constant be k = 1 L/s.mol, and the nominal values of the feed stream Fio = 10 L/s and Caio = 2 mol/L. The reactor is normally run so as to achieve 65% conversion (i.e., 35% of A leaves unreacted). c) By hand calculate the nominal steady state d) Repeat (c) by using Excel's Solver tool
