1. The gas phase irreversible isothermal (420K) reaction, A+2B-2R is first order in both A and B is investigated using a constant volume batch reactor. For a particular test the reactor is charged with a stoichiometric mixture of gas A and B and an inert gas I, and the total pressure is monitored as the reaction proceeds. The results for the test run were as follows, Time Total Pressure t/h p/atm 0.0 5.0 0.5 3.81 1.0 3.70 1.5 3.66 2.0 3.64 3.57 The final reading was taken after the reactor was left overnight and the temperature was maintained at 420 K. (a) From the above Table of experimental data determine the initial composition of the gases in the reactor. [20%] (b) Using the tabulated data verify that the rate constant for the conditions reported above has a value of 0.0431 m2/(mol-h). [30%] (c) A PFR and a CSTR, each with the same volume of 10 m?, are connected in series. It is found that the concentration of reactant A, CA1, coming from the PFR is 13.19 mol/mWhat overall conversion, and production rate of R is achievable with this reactor cascade? You may assume that the feed temperature and pressure are 420 K and 5 atm respectively, and the feed composition is that which was found in (a) above. [50%] 00
