Question 1 a) Explain four (4) important performance cycle steps that a batch reactor can basically be described by during its operation. [8 marks b) The following second order reaction (first order in each reactant): A + 2B - P is conducted in a rigid batch reactor at constant temperature. The rate of reaction (consumption of A) is given by -A = k CACB [mol/l.n] with Reaction rate constant k k = 2 4mot The shutdown time ts (for oftloading cleaning and charging the reactor batches) ts = 1 hour Determine the batch reaction time required to achieve 95% conversion if we premix the renctants in stoichiometric ratio in the batch before we start the reaction. Reactant A is liquid with Cho = 2 mol/, and Reactant B is also liquid with Ceo = 4 mol/, prior to mixing. Both reactants are liquid and completely miscible and have the same densities. [Note: your Cao and Coo at the start of the batch reaction are obtained by mixing these reactants. The density remains constant. ] (17 marks
