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.)
