When Henry's law constant is higher, how is the solubility of a gas at the same pressure considered?
Answer and explanation
Correct answer: Lower
Using the common form p = KH x, the dissolved mole fraction is x = p/KH. At the same gas pressure p, increasing KH therefore makes x smaller, which means lower solubility. This interpretation assumes the same temperature and the same convention for Henry's constant; some texts define a reciprocal constant, so the formula must be checked before comparing numerical values. Under the convention used here, A is correct.
