(a) 0.1

(b) 0.2

(c) 100

(d) 500

I had been asked this question during an interview for a job.

My question comes from Vapor-Liquid Equilibria in Binary Systems in division Two Phase Gas – Liquid Systems, Phase Rule and Vapor-Liquid Equilibria of Basic Chemical Engineering

Answer 1

The correct answer is (b) 0.2

For explanation I would say: K = 10/50 = 0.2.
