Show hintHide hint
Think about how pressure influences solubility.
Question 2.
What is Raoult's Law?
Show hintHide hint
It involves the pure components' vapor pressure.
3Question 3.
What does Henry's Law state?
- Gas solubility is inversely proportional to pressure.
- Gas solubility is directly proportional to pressure.
- Gas solubility is independent of pressure.
Show hintHide hint
Remember the relationship between gas pressure and its solubility.
4Question 4.
