1. Find the fugacity of a liquid A in water. The concentration of A in water is 1 mg/L. The molecular weight of A is 78. The vapor pressure of A is 0.02 atm. Assume that A behaves ideally in water.
2. For the reaction H2S(g) → H2S (aq), the enthalpy of dissolution is -19.2 kJ/mol at 298 K. If the temperature is raised to 318 K, by how much will the equilibrium constant of the reaction change?
