Before carrying out any calculations, make a sketch as to what you expect the molar flow rate profiles to look like



Solution


A is consumed in reactions 1 and 2, so Fa will steadily decrease

B is consumed in reaction 1, and once A is consumed, it will no longer be able to react and the flow rate will remain constant

C is produced in reaction 1, consumed in reaction 2, and therefore the molar flow rate will go through a maximum will also no longer be consumed once A is used up

D will be produced once C is formed and will continue to increase until A is consumed

You may want to solve for these profiles quantatatively by using Polymath
