The enthalpy of solution of KBr in water is about +198 kJ/mol (endothermic). Nevertheless, the solubility of KBr is relatively high. Explain why. A sample consisting of various gases contains 3.5*10^-6 mole fraction of radon. This gas at a total pressure of 36 atm is shaken with water at 30 degree C. Assume that the solubility of radon in water with 1 atm pressure of the gas over...
