Question

Please answer 12-17 and show work. I’m not sure which equations to use

15. The gas above the liquid in a sealed bottle of soda is primarily carbon dioxide. Carbon dioxide is also dissolved in the soda. When the distribution of carbon dioxide between the gas and liquid is hase , , at equilibrium, molecules ofcarbon dioxide in the gas phase can stilldissolve in the iquid they strike the surface and are captured. Similarly, molecules of carbon dioxide can escape the liquid phase. What is the entropy change of the universe, ASni, for the dissolution of carbon dioxide under these conditions? Explain your answer. 16. The enthalpy and entropy of vaporization of acetone at its normal boiling point, -56.4°C, are 31.3 kJ/mol and 95.0 J/mol K, respectively. What would the entropy change of the universe be if one mole of acetone vapor were to condense in a large room maintained at 25.0°c? 17. The enthalpy and entropy of vaporization of water at 100.00°C are 40.66 kJ/mol and 109.0 J/mol K, respectively. What is the entropy change of the universe when one mole of steam condenses in a large room maintained at 25.00°C? Assume the final temperature of the water is 100.00°G.
