Consider the reaction

A→D -->→U

Pure A is fed to a 1.0 dm3 CSTR where it reacts to form the desired product (D), which can then react further to produce an undesired product (U); both reactions are elementary and irreversible and everything is the liquid phase. The entering concentration of A is 1 mole/dm3 at a molar flow rate of 1 mol/min. (a) Sketch graphs of the conversion of A, X, the instantaneous selectivity of D to U, SD/U, and the instantaneous yield of D, YD, as a function of space-time (make sure to label them on the plot). You may want to write a sentence or two of reasoning for partial credit purposes.
