Consider the isothermal expansion of 4.50 mol of an ideal gas at 450 K from an initial pressure of 12.0 bar to a final pressure of 2.75 bar. Describe the processes that will result in the greatest amount of work and least amount of work being done by the system with a constant external pressure and calculate w. Then what is the least amount of work done without restrictions on the external pressure? SHOW ALL WORK.
