Question

The end of an equilibrium curve is called as

(a) Critical point

(b) Triple point

(c) End point

(d) Single point

I have been asked this question in an internship interview.

This key question is from Problems When Setting Simulation Input in portion Rigorous Distillation Calculations of Distillation Design

Answer 1

Right choice is (a) Critical point

The explanation is: A critical point is the end point of a phase equilibrium curve, while the point where all three phases of water coexist is called as triple point and final stages of any curve are called as end point.
