Chapter 2, Problem 2.32NP

Consider the isothermal expansion of 2.35 mol of an ideal gas at 415 K from an initial pressure of 18.0 bar to a final pressure of 1.75 bar. Describe the process that will result in the greatest amount of work being done by the system with ${\text{P}}_{\text{external}}\ge 1.75bar$, and calculate w. Describe the process that will result in the least amount of work being done by the system with ${\text{P}}_{\text{external}}\ge 1.75bar$, and calculate w. What is the least amount of work done without restrictions on the external pressure?
