Which of the following is not a fluid – fluid reaction?
(a) Reaction of chlorine with benzene to produce chlorobenzene
(b) Soap formation by action of aqueous alkali on fatty acids
(c) Action of ammonia on aqueous nitric acid
(d) Combustion of coal
I had been asked this question in a job interview.
This intriguing question comes from Design of Fluid Fluid Reactors in chapter Fluid-Fluid Reactions: Kinetics & Basics of Non Ideal Flow of Chemical Reaction Engineering
