For the elementary reaction: 2

1.1 If the reaction is elementary and irreversible, what is the rate of reaction with respect to A? [2]

1.2 If the reaction is elementary and irreversible, write an equation that relates rB to A. What is the rate of reaction with respect to B? [3]

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

1.4.The above reaction will be done in a flow reactor. There is B in the feed so that the ratio of B0 to A0 is 1 to 4. Draw up a stoichiometric table for the flow reactor. There are no inert components in the reactor feed. [8]

1.4.2 The liquid phase reaction will be done under isothermal conditions at constant density. Write an expression for the rate of reaction of A in terms of A and . [3]

1.4.3 The final conversion is 80%, 0 is 50 L/s and the value for f is 0.0050 s-1 .
