1. Calculate the number of possible microstates in system (A): one particle and four slots. 2. Calculate the number of possible microstates in system (B): three particles and four slots. 3. 4. Calculate the entropy difference between the two systems (A) and (B). Systems A and B, are combined into system C, shown above. Calculate the total number of microstates when (A) and (B) are merged together to give (C). 5. If two quanta of energy are added to this system, Wotal = Wparticles X Wquanta Energy quanta can pass between the two subsystems, but particles cannot. Energy quanta can only be located on a particle, not in an empty box. You may add as many quanta as you like o any given particle. Calculate the total number of unique energy arrangements W of system C. 6. The barrier between the two parts of system C is removed so that particles can move throughout the combined system. Calculate the total number of unique arrangements Wtotal.
Discuss the diagram of the molar Gibbs free energy (or chemical potential) versus temperaturebelow for a pure substance. Why are there three curves? Why do they slope downward? Does thegraph identify any interesting temperatures? Are some segmentsof the curves more important/interesting than others? Feel free to redraw and label the diagram.
At 363 K, one state is twice as likely as the other. The first (more likely) state has an energy of 9.19 kcal/mol and an entropy of 0.915 kcal/mol-K. The other state has an energy of 2.19 kcal/mol more then the first state. What is the entropy of the second (less likely) state?
For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. System A few grams of ammonia vapor (NH3). A few moles of nitrogen (N₂) gas. A few moles of nitrogen (N₂) gas. Change The ammonia condenses to a liquid at a constant temperature of -8.0 °C. The nitrogen is cooled from 78.0 °C to 3.0 °C while the volume is held constant at 2.0 L. The nitrogen is heated from -16.0 °C to 12.0 °C and also expands from a volume of 1.0 L to a volume of 10.0 L.
