Question

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 would the concentration of the desired product be in the CSTR from a)?
c) (2 points) What conditions and reactors could be used to maximize the selectivity of the desired product? Justify your answer.
