For an isothermal expansion of 1.00 mole of ideal gas at 399K and initially at 16.00bar pressure, compare the total work done by the system if the expansion is carried out:
a. reversibly to 1.00 bar
b.Irreversibly as 3 steps, first against an external pressure of 11.00 bar, then 6.00 bar, then 1.00 bar
