A goes to Desired, Desired goes to Undesired.

Could someone please explain the plots?

Q 3: Consider the following reaction A D ; kl=1.1 D U;k2=1.2 Pure A is fed to a 1.0L CSTR where it reacts to form a desired product (D), which can then react further to produce an undesired product (U); both reactions are elementary and irreversible, and everything is in the liquid phase. The entering concentration of A is 1mole/L at a molar flow rate of 1 mol/min. a) Sketch the conversion of A, X, the instantaneous selectivity of D to U, SD/U, and the instantaneousyield of D, YD, as a function of space-time (make sure to label them on the plot). b) (b) If at =1.0 minutes the instantaneous selectivity, SD/U, is (1/2) and the conversion of A is (0.5), what are the specific reactions rates k1 and k2
