Henry's constant water
WebHenry’s Law Constant The constant (k} is determined through experimentation. The gas pressure above the liquid is carefully controlled, and then the concentration in the solution is measured. The constant is experimentally determined by dividing the concentration by the partial pressure at different points. WebHenry's Law constant (water solution) k H (T) = k° H exp(d(ln(k H))/d(1/T) ((1/T) - 1/(298.15 K))) k° H = Henry's law constant for solubility in water at 298.15 K (mol/(kg*bar)) d(ln(k …
