For the elementary reaction: A + B 3C [2] 1.1 If the reaction is elementary and irreversible, what is the rate of reaction? 1.2 What is delta (8) for the reaction? [1] 1.3.1 The above reaction will be done in a batch reactor. Draw up a stoichiometric table for the batch reactor. Make provision for the presence of an inert component in the reactor. [12] 1.3.2 The batch reaction will be done under isothermal conditions at constant volume. Write an expression that describes how pressure varies with conversion. [3] 1.3.3 The final conversion is 80%, the initial number of moles of A is 0.25 mol and I is 0.50 mol, there is no C present and, A and B are present in a 1:1 ratio. i) Calculate the percentage increase (decrease) in the final pressure relative to the initial pressure. [4] ii) The volume of the batch reactor is 5 L and the rate constant is 0.023 L.mol-.s. The reaction will be done in a gas phase, isothermal batch reactor. For a conversion of 80%, how much time is required? [15] 1.4.1 The reaction will be done in a gas phase, isothermal plug flow reactor. Derive an expression for the volume of the reactor. The molar ratios of the feed components (A, B and I) and temperature will be kept the same as for the batch reactor in Q1.3.3. Take the pressure in the reactor as constant. [10] 1.4.2 The flowrate to the PFR is 20 L/s and the required conversion is 80%. Explain how you would find the reactor volume. [3] [Question 1 = 50 marks]
