a) 1.00 g H2 and 1.00 g O2

Q1.3) Why is the possibility of exchange of matter or energy appropriate to the variable of interest a necessary condition for equilibrium between two systems?

Equilibrium is a dynamic process in which the rates of two opposing processes are equal. However, if the rate in each direction is zero, no exchange is possible, and therefore the system can not reach equilibrium.

In this case, the well depth is a small fraction of the total energy. Therefore, the particle is unaffected by the attractive part of the potential.
Q1.5) The parameter a in the van der Waals equation is greater for H2O than for He. What does this say about the form of the potential function in Figure 1.6 for the two gases?

1-cm-thick vacuum < 1-cm-thick cork < 1-cm-thick concrete < 1-cm-thick copper

P1.1) A sealed flask with a capacity of 1.00 dm3 contains 5.00 g of ethane. The flask is so weak that it will burst if the pressure exceeds 1.00 × 106 Pa. At what temperature will the pressure of the gas exceed the bursting temperature?
It says that the depth of the attractive potential is greater for H2O than for He.

Q1.4) At sufficiently high temperatures, the van der Waals equation has the form . Note that the attractive part of the potential has no influence in this expression. Justify this behavior using the potential energy diagram in Figure 1.6.

Q1.1) The location of the boundary between the system and the surroundings is a choice that must be made by the thermodynamicist. Consider a beaker of boiling water in an airtight room. Is the system open or closed if you place the boundary just outside the liquid water? Is the system open or closed if you place the boundary just inside the walls of the room?

Q1.2) Real walls are never totally adiabatic. Order the following walls in increasing order with respect to being diathermal: 1-cm-thick concrete, 1-cm-thick vacuum, 1-cm-thick copper, 1-cm-thick cork.
c) 1.00 g CH4 and 1.00 g NH3

P1.2) Consider a gas mixture in a 2.00-dm3 flask at 27.0ºC. For each of the following mixtures, calculate the partial pressure of each gas, the total pressure, and the composition of the mixture in mole percent.

Problems
Problem numbers in italics indicate that the solution is included in the Student’s Solutions Manual.
b) 1.00 g N2 and 1.00 g O2

If the system boundaries are just outside of the liquid water, the system is open because water can escape from the top surface. The system is closed if the boundary is just inside the walls, because the room is airtight.
