The answer for H(3) is minus 1.26 KJ/mol. Demonstrate the reference state to the process state for nitrogen gas. I know that is an ideal gas law for the nitrogen gas. I know how to calculate the heat capacity for this.
Q. VI: An equimolar liquid mixture of benzene and toluene is separated into two product streams
by distillation. At each point in the column some of the liquid vaporizes and some of the vapor
stream condenses. The vapor leaving the top of the column, which contains 97 mole% benzene,
is completely condensed and split into two equal fractions: one is taken off as the overhead
product stream, and the other (the reflux) is recycled to the top of the column. The overhead
product stream contains 89.2% of the benzene fed to the column. The liquid leaving the bottom
of the column is fed to a partial reboiler in which 45% of it is vaporized. The vapor generated in
the reboiler (the boilup) is recycled to become the rising vapor stream in the column, and the
residual reboiler liquid is taken off as the bottom product stream. The compositions of the streams
leaving the reboiler are governed by the relation,
YB/(1 - YB)
XB/(1 - XB)
= 2.25
where YB and XB are the mole fractions of benzene in the…
Q. IV: Aqueous solutions of the amino-acid L-isoleucine (Ile) are prepared by putting 100.0 grams
of pure water into each of six flasks and adding different precisely weighed quantities of lle to
each flask. The densities of the solutions at 50.0±0.05°C are then measured with a precision
densitometer, with the following results.
r (g lle/100 g H2O) 0.000
p (g solution/cm³)

0.98803 0.98984

(a) Plot a calibration curve showing the mass ratio, r, as a function of solution density, p, and fit a
straight line to the data to obtain an equation of the form r = ap + b.
(b) The volumetric flow rate of an aqueous lle solution at a temperature of 50°C is 150 L/h. The
density of the sample of the stream is measured and found to be 0.9940 g/cm³. Use the calibration
equation to estimate the mass flow rate of lle in the stream (in kg lle/h).
(c) It has been later discovered that the thermocouple used to measure the stream temperature…
