134. Which of the following doesn’t apply to Henry’s law?
  1. k changes based on the type of gas and temperature,
  2. Increasing pressure increases the partial pressure of the gas
  3. The concentration of dissolved gas also depends on the solvent; some gases dissolve easier in water than other solvents
  4. At constant temperature, C1/P1=C2/P2
  5. The value of k for CO2 is the same for water and ethanol
