1
Q
Henry’s Law: definition
A
The concentration of gas in a solution is directly proportional to its solubility and partial pressure
2
Q
Henry’s Law: equation
A
C = alpha(P)
3
Q
Fick’s Law: definition
A
Diffusion of a gas is directly proportional to surface area and partial pressure
Diffusion is inversely proportional to thickness
