Henry's Law

Written by Jerry Ratzlaff on . Posted in Thermodynamics

henrys lawHenry's law, one of the gas laws, at a constant temperature, the volume of a gas which will dissolve into a solution is directly porportional to the partial pressure of that gas above the solution in equilibrium with the liquid.


Henry's Law formula

\(\large{ C =  k \; P  }\)   


 Units English Metric
\(\large{ C }\) = concentration of the solubility (gas) at a fixed temperature in a partial solution \(\large{\frac{mol}{gal}}\) \(\large{\frac{mol}{L}}\)
\(\large{ k }\) = Henry's law constant - \(\large{\frac{mol}{m^3-Pa}}\)
\(\large{ P }\) = partial pressure of the gas \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
