should I use 250 cm^3 or 500 cm^3
1. Consider a container of volume 250 cm that is divided into two compartments of equal size. In the left compartment there is argon at 100 kPa and 0 °C; in the right compartment there is neon at the same temperature and pressure. Calculate the entropy and Gibbs energy of mixing when the partition is removed. Assume ideal mixing and that both gases are ideal.

A rectangular box is divided into three spaces that are separated by two barriers. The first space constitutes half the volume of the box, while the second and third spaces each constitute one quarter of the volume. Initially, 2 moles of oxygen are placed in the first space, 1 mole of nitrogen is in the second space, and 1 mole of argon is placed in the final space. After the system is setup, the partitions are removed and the gases...

5. An ideal gas is confined to a container whose volume is fixed. If the container holds n moles of gas, by what factor will the pressure increase if the absolute temperature is increased by a factor of 2? (A) 2/(nR) (B) 2 (C) 2nR (D) 2/n (E) 2/R 6. Two large glass containers of equal volume each hold 1 mole of gas. Container 1 is filled with hydrogen gas (2 g/mol), and Container 2 holds helium (4 g/mol). If...

I thought when A has 2 mol and B has 1mol
mole fraction would be 2/3 for A and 1/3 for B
then the result is
delta S = -R (3N)*((2/3)ln(2/3) + (1/3)ln(1/3))
(and this was actually the answer of (4)!)
but the result is 3Rln(2).

Problem: 4.1 A rigid container is divided into two compartments
of equal volume by a partition.
One compartment contains 1 mole of ideal gas A at 1 atm, and the
other

entropy which
occurs when the partition between the two compartments is removed.
If the first
compartment...
