Reaction 1: A + B --> E + 0.3 F with rF = 7.5 CA1.5CB1.5

Reaction 2: A + B --> 0.3 C + D with rD = 0.5 CA2CB0.5

These are parallel liquid-phase reactions. It occur in a 0.3 m3 plug flow reactor. The initial concentrations of A and B are each 17 mol L-1.  What is the instantaneous selectivity of desired compound F over the undesired compound D, assuming that the conversion X is 0.87 ?

During the liquid phase decomposition of A, two reactions compete. A one-half order reaction (k1 = 0.025 mol1/2/L1/2/sec) produces the desired product; whereas, a first order reaction (k2 = 0.008/sec) produces an unwanted impurity. The initial concentration of A to be used is 8 mol/L and 75% conversion of A is required. a) (7 points) If a CSTR is used to achieve this conversion, what would be the overall yield and selectivity of the desired product? b) (4 points) What...
