Henry's Law question?

Question

The lowest value of the Henry's Law for methane gas (CH4) will be obtained with ________ as the solvent and a temperature of _______ K.

C5H12, 301

C6H6, 322

C6H6, 349

H20, 301

H20, 349

Answer 1

C5H12 at 301 K. Methane gas is not soluble in water, therefore the solvent cannot be H2O; Henry's Law is temperature dependent as partial pressure increases as temperature increases, 301 K will give the lowest partial pressure.
