The Antoine Equation is often used to calculate the saturation
pressure of a pure species at a given temperature. Use the
thermodynamic knowledge you have gained to explain what
thermodynamic properties the Antoine coefficients represent.
Given cyclopentane at 1000kPa, calculate the following:
a) The saturation temperature associated with the pressure that
you were given, assuming that the system is in vapour-liquid
equilibrium. Use an equation of state method to solve this
problem.
b) The molar volume of the vapour and liquid phase.
d) The fugacity at saturation.
Draw an oxygen saturation curve for hemoglobin (pressure of O2
versus saturation (y)) with physiological levels of CO2 and 2,3-BPG
at biological pH. Now using arrows to indicate which direction it
moves, draw the shift in this curve when:
a) There is a decrease in CO2
b) There is an increase in 2,3-BPG
c) There is an increase in pH
d) Hemoglobin experiences a loss of quaternary structure (breaks
up into monomers)
Calculate the normal boiling point of liquid Q if the vapor
pressure is .500 atm at 20 degrees C. The change/ delta of H of
vaporization for liquid Q is 26 kJ/ mole. Do you except liquid Q to
have H bonds?

A feed mixture containing 40 mol% heptane and 60 mol% ethylbenzene
is to be fractionated at 1 atm pressure to produce a distillate
containing 95 mol% heptane and a bottom product stream containing
96 mol% ethylbenzene.
Determine the minimum reflux ratio if the feed...
The reaction F + G = H is at equilibrium, under standard
conditions.
(a) Calculate ∆Go’ if [F] = 2mM, [G] = 3 mM, and [H] = 9 mM
(b) What happens to ∆Go’ if the solution is at equilibrium at
twice this concentration of F?
(c) What happens to ∆Go’ if the solution is at equilibrium at
twice this concentration of H?
(d) Does this violate LeChatelier’s Principle?
