For elementary reaction: A + B = 3C

1.1 If the reaction is elementary and reversible, what is the rate of reaction?

1.2 What is delta for the reaction?

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.

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.

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 1:1 ratio.

i) Calculate the percentage increase (decrease) in the final pressure relative to the initial pressure.

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 conversion of 80%, how much time is required?

1.4.1 The reaction will be 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.

1.4.2 The flowrate to the PFR is 20L/s and the required conversion is 80%. Explain how you would find the reator volume.
