Document Summary
3. 4 explain the significance of the clapeyron equation and the clausius clapeyron equation. Why do they not depend on the chemical identity of the solute?- 3. 11 calculate the change in molar gibbs energy of carbon dioxide (treated as a perfect gas) at. 20 c when its pressure is changed isothermally from 1. 0 bar to (a) 2. 0 bar and (b) 0. 000 27 atm, its partial pressure in air. 3. 12 the standard molar entropies of water ice, liquid, and vapor are 37. 99, 69. 91, and 188. 83 j. On a single graph, show how the gibbs energies of each of these phases vary with temperature. Hint: express the entropy of fusion in terms of the enthalpy of fusion and the melting point of ice. 3. 21 a thermodynamic treatment allows predictions of the stability of dna. The table below lists the standard gibbs energies, enthalpies, and entropies of formation at 298 k of short sequences of base pairs as two polynucleotide chains come together:
