How can temperature adjustments be made to improve Henry’s law constan

[ILove Chemistry]

I missed an answer to a question when professor was going through it
at the end of a lecture (for a grad level Analytical Chem class)The
question is related to Henry's Law.

Q: How can temperature adjustments be made to improve Henry’s law
constants for trapping or desorbing gases?

Since K is a function of T (Temperature) , I'd say that if you want to
change K, change T. Changing (increase or decrease in T to change K to
desired direction) must be done according to the solubility of the
gas. For example, Oxygen dissolves better in cold water. So,
decrease the T to increase K for .
Am I right?

That's right - so far.

That depends, because various equations are existing - reciprocal
equations. That means either k increase or decrease ;-)
