Question

Which of the following is not a characteristic of tracer?

(a) Inertness

(b) Non – reactive

(c) Easily detectable

(d) Adsorbance onto the reactor surface

I got this question by my college director while I was bunking the class.

This question is from Non Ideal Flow Basics in division Fluid-Fluid Reactions: Kinetics & Basics of Non Ideal Flow of Chemical Reaction Engineering

Answer 1

The correct choice is (d) Adsorbance onto the reactor surface

To explain: The tracer should not stick to the walls or other surfaces of reactor. The physical properties of the tracer should be similar to that of the system.
