Homework Set 8 (FINAL HOMEWORK SET)
Assigned April 25, Thursday, 2001
Solutions due in class on May 1 (Wed)
Problems
-9.2 (note: for calculations, assume mixtures behave as ideal solution; also, for completeness, read section 9.6 in the book on deviations from Raoult's Law for ideal solutions)
-9.3
-9.5 (note: optionally,
you could solve this problem using FLSHR.xls, the spreadsheet emailed to
the class on April 24- however, you may need to override the Ki
calculations in FLSHR).

Homework Set 7
Assigned Wednesday, April 10, 2002
Solutions Due (in Class), Monday April 22, 2002 (Note, the deadline was originally April 17)
Problems:
(i) Explain in less than 100 words why dG(liq) = dG(vap) during
liquid-vapor phase equilibrium, when
temperature is increased? (You may use an illustration or an equation
to support your answer).
(ii) 8.1
(Hint: For 8.1, use the Clayperon
Equation for solid-liquid phase, that is, in terms of heat of fusion (instead
of vaporization) during ice melting. Assume that Vl-Vs and Hl-Hs
are constant wrt P).
(iii) 8.2
(iv) 8.4
(v) 8.5
(vi) 8.7
(vii) 8.12
(Hint: For 8.12, plot P (from
0.01 to 10 MPa) vs. H (0 to 40000 J/mol) graphically in Excel, using data
derived from PREOS.xls.)
