Question

According to Hendry’s law,

(a) Y=(p/P)

(b) Y=(p* P)

(c) p=(Y/P)

(d) p=(Y*P)

This question was addressed to me by my college director while I was bunking the class.

This interesting question is from Gas-Absorption Principle topic in portion Gas Absorption of Mass Transfer

Answer 1

Right answer is (a) Y=(p/P)

The explanation: For a straight line Y=m*x, the law proved by Hendry. (i.e.) Y=(y/P) =m*x.

Where, Y=equilibrium mole fraction in vapour

               pA= partial pressure

               P= Total pressure.
