The origin of the question is Kinetics of Homogeneous Reactions topic in chapter Kinetics of Homogeneous Reactions of Chemical Reaction Engineering

Answer 1

The correct answer is (a) There is no axial mixing in a plug flow reactor.

The best I can explain: There is no mixing of early and later entering fluid in a plug flow reactor. There is no overtaking between the fluid molecules.
