For the elementary reaction: + 2 3

2.1 If the reaction is elementary and irreversible, what is the rate of reaction? [2]

2.2 What is delta () for the reaction? [1]

2.3.1 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]

2.3.2 The batch reaction will be done under isothermal conditions at constant volume. Will the pressure in the reactor change as the reaction proceeds? Justify your answer.
