Trying to look at Henry's law constants and there seem lots of equations involved.
One involves vapor presure, the other partial pressure - just wondering what the differnce is

Given a vessel containing a mixture of gases, the partial pressure of each gas is the pressure that would be in that vessel if you removed all the other gases except the one. I.e., a rough measure of how many particles of a given gas are present, more particles, greater partial pressure.
vapour pressure is the pressure of the vapour of a liquid at equilibrium with it's liquid phase in a vessel. I.e., a rough measure of how strongly the liquid wishes to evapourate. The more volatile the liquid, the higher the vapour pressure.

When a liquid starts evaporating then vapours are formed and there come a point at which molecules becoming vapours becomes equal to molecule coming back to liquid. At this point the vapours become saturated and is called the vapour pressure or saturated vapour pressure.
Partial pressure is the pressure of a gas or vapour in a mixture with other gases. This is the indiviual pressure of any gas...
Example: in atmospheric air, it is the sum of partial pressure of dry air and water vapours

Vapour pressure is the property of a liquid giving off a gas. Partial pressure is the pressure of a gas (as if it were alone in the container).

Partial is when you have a mixture of gases. They add up to the total vapor pressure

They are two different words-partial ie 'quite fond of' and vapour ie 'fainting fit'. I haven't heard of Henry or his constant brushes with the law. You are not alone in wondering about this question. Everybody does at some point.
