If a component has positive deviations from Raoult's law, then for the same component:

The Henry's law activity coefficient will approach one when the Henry's law component is pure.

The Henry's law activity coefficient for will be less than or equal to one.

Nothing can be assured about the size of the Henry's law activity coefficient.

Since Henry's law is a straight line, the activity coefficient is always one.

If the Lewis$-$Randall $($L$-$R$)$ activity coefficients are known for a binary system, then for the component to be modeled with Henry's law,

The slope of the Henry's law activity coefficient will be opposite of the L$-$R gamma for the same component.

The curvature of the Henry's law activity coefficient will be exactly the same as the curvature of the L$-$R gamma for the same component.

The Henry's law activity coefficient will be the negative of the L$-$R gamma for the same component.

The Henry's law activity coefficient will differ from the L$-$R gamma for the same component in a complicated way.
