Question

Calculate molar volumes of ethane at 320 K from 10 kPa to 20000 kPa at 200 kPa intervals using the Peng-Robinson and Redlich-Kwong-Soave equations of state. Note: I would love to have the values for molar volume.

Answer #1

Calculate the pressure exerted by benzene for a molar volume of
2.4 L at 600. K using the Redlich-Kwong equation of state:
P=RTVm−b−aT√1Vm(Vm+b)=nRTV−nb−n2aT√1V(V+nb)
The Redlich-Kwong parameters a and b for benzene
are 452.0 bar dm6 mol−2 K1/2 and 0.08271 dm3 mol−1,
respectively.
Is the attractive or repulsive portion of the potential dominant
under these conditions?

Use both the van der Waals and the Redlich-Kwong equations to
calculate the molar volume of CO at 213 K and 1036 bar. (Take
a = 1.4734 dm6·bar·mol−2 and
b = 0.039523 dm3·mol−1 for the van
der Waals equation and A = 17.208
dm6·bar·mol−2·K1/2 and B
= 0.027394 dm3·mol−1 for the Redlich-Kwong
equation.)
Calculate the molar volume under the same conditions using the
ideal-gas equation.
Answer in dm3·mol−1.

Cracking of ethane is very big business, as can be seen from the
construction of the Shell cracker plant just outside Pittsburgh.
The basic reaction is
C2H6 =
C2H4 + H2

reaction and the equilibrium constant at standard conditions using
the data in Koretsky
(b) Write down the expression for the equilibrium constant in
terms of the extent of reaction and the system pressure, assuming
ideal gas behavior. Assume...

A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8)
and 15% butene (C4H8) by volume. It is to be fed to the combustion
chamber in 10% excess air at 25ºC, where it is completely burnt to
carbon dioxide and water. The flue gases produced are to be used to
generate 5 bar steam from water at 90ºC.
(a) Write balanced equations for the combustion of each
component of the fuel gas.
(b) Explain the need for excess air....

3) Now you will plan for your retirement. To do this we need to
first determine a couple of values.
a. How much will you invest each year? $1,000 a year is
what i will invest.
State what you will use for P, r, and n to earn credit. ( The
typical example of a retirement investment is an I.R.A., an
Individual Retirement Account, although other options are
available. However, for this example, we will assume that you are
investing...

Fancy Millwork has a factory that produces custom kitchen
cabinets. It has multiple product lines. Materials and labor for
the cabinets are determined by each job. To simplify the
assignment, we will assume the following average costs. The company
estimates that it will have 32,000 direct labor hours in total for
the kitchen cabinets. The materials include $2,000 for the wood and
other materials on a per job basis. It requires 40 hours of labor
on average for a custom...

Part I. Indicate whether true or false (T or F).
____ Storm water detention ponds typically are designed to
regulate the outflow peak rate at or below a single target value,
such as the pre-development (pre-land use change) peak runoff rate
for a specified return period event. Detention storage alters the
peak but not the volume of the outflow hydrograph.
_____ Typical rating curves for weirs are concave upward.
Typical rating curves for orifices are concave downward.
____ A sediment...
