2. . The liquid phase decomposition of reactant A takes place according to the following parallel reaction scheme, A2R Tp = KCA 2A-S Is = K₂ In a series of CSTR test runs in which the feed concentration of A, CAO, was kept at 2.0 mol/L, the volumetric flow rate of the feed, Q., was varied, and the exit concentrations of products, and were measured. The following Table summarises this series of experimental test results, dh 0.000 0.121 0.320 0.706 1.778 CRCAO | 0.000 | 0.097 | 0.192 | 0.282 | 0.356 CsCAO | 0.000 | 0.012 | 0.032 | 0.071 |0.178 Q2 is continued overleaf...... Page 2 of 7 (a) Determine the fractional conversions achieved at each of the space-times in the above table of experimental results. (10%) (b) Verify that the values of the rate constants, ka and k2, are 1.0 and 200.0 respectively and state the units for each rate constant? [20%] (c) The maximum concentration of the desired product occurs at a fractional conversion of 0.865, calculate the space time and yield of product, R, defined as 2CR CAXA at this fractional conversion. [20%] (d) Compare the values obtained in (c) for those that would be achieved by a PFR designed for the same feed conditions and fractional conversion. [40%]
