Answer #1

If the first reaction, A + 2B = C, is fast, that is the conversion of A to C is a fast reaction. We would have a large amount of C available that would form D. The selectivity of D would be higher in such cases than C. In case we have a low fractional conversion of A. The amount of C present at a given time would be greater than D. Such that the selecticity of C is greater when the fractional conversion of A is low and the selctivity of D is greater when the fractional conversion of A is greater.

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...
