Chapter 18, Problem 18.122MP

Interpretation Introduction

Interpretation:

The Henry’s law constant for hydrogen has to be calculated.

Concept Introduction:

Henry law:

Henry law can be defined as the amount of dissolved gas is proportional to its partial pressure in the gas phase.  The proportionality factor is called as Henry’s law constant.

The henry law constant is given by the equation,

${\text{H}}_{\text{cp}}\text{=}\frac{{\text{C}}_{\text{a}}}{\text{p}}$

Where

$\begin{array}{l}{\text{H}}_{\text{p}}\text{=}\text{Henry}\text{law}\text{constant}\left(\text{mole/}\left(\text{L}\text{.atm}\right)\right)\\ {\text{c}}_{\text{a}}\text{=}\text{concentration}\text{of}\text{species}\text{in}\text{aqueous}\text{phase}\\ \text{p}\text{=}\text{partial}\text{pressure}\text{of}\text{the}\text{species}\\ \end{array}$
