= = Assume that a bimolecular, irreversible reaction A+B C takes place at steady state in a liquid film of thickness L. Reactant A is introduced at x 0 and reactant B at x L. The liquid solution is dilute everywhere with respect to solutes A, B, and C. The volumetric rate of formation of C is given by Rv = kCACB where k is the second-order, homogeneous rate constant. If the reaction kinetics are extremely fast, A and B cannot coexist in the liquid. In this limit, the reaction occurs at a plane x = XR, dividing the liquid film into two parts, and forms a boundary between the part of the film that contains A (but not B) and the part that contains B (but not A). Determine XR, CA(x), CB(x), and the reaction rate. NOTE: The problem should be modeled as a one-dimensional system
