The correct answer is The solubility will increase.
What is henry's law?
Henry's law, asserts that at constant temperature and for a particular kind and volume of liquid, the amount of a given gas that dissolves in the latter is precisely proportional to the partial pressure of the gas in equilibrium with the former. The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid, which is an equivalent way to state the law:
C=kPgas
Thus, as the solubility is directly proportional to the pressure hence the solubility of RbI will increase.
