Question

: Henry's law constant of CO, in water at 298 K is
5K bar. If pressure of Co, is 0.01 bar, find
its mole fraction​

Answer 1

Given

• Henry law constant of water = 5 bar.

• Pressure of CO in water = 0.01 bar.

To Find

Its mole fraction in the solution.

Formula

$P = K_h \times X$

• Where ,X is mole fraction of CO in water.

• While $K_h$ is henry constant.It increases with increase in temperature

Calculations

$P = K_h \times X \\ \\ \\ =>\: 0.01\:=\:5 \times X \\ \\ \\ => \: X = \dfrac{0.01}{5} \\ \\ \\ => \: X\:=\:0.002$

Hence, mole fraction of CO in water is 0.002 .
