Maximizing the Selectivity - Parallel Reactions

Determine the instantaneous selectivity, SD/U, for the liquid phase reactions:

Sketch the selectivity as a function of the concentration of A. Is there an optimum and if so what is it?

Hint 1: Write the equation for selectivity

Hint 2: Sketch the selectivity as a funtion of CA
