(d) p – H

This question was addressed to me by my school principal while I was bunking the class.

My doubt is from Vapor-Liquid Equilibria in Binary Systems topic in portion Two Phase Gas – Liquid Systems, Phase Rule and Vapor-Liquid Equilibria of Basic Chemical Engineering

Answer 1

The correct option is (b) p/H

Explanation: According to Henry’s Law, p = H*x, => x = p/H.
