There is the irreversible elemental reaction in the liquid phase A+B+C+D that is carried out isothermally in a 16L PFR. The current that enters the PFR comes from a 4L CSTR that acts as a premix tank, where two streams are fed with the same volumetric flow, one containing 0.02 mol/ L of A and the other containing 1.4mol/L of B. In the premix tank, the reaction begins to be carried out, so that at its outlet it is already has a concentration of 0.02mol/L of C. Determine what the concentration of C will be and the conversion of A achieved at the outlet of the PFR. (20 points)
