Question

Consider 1.00 mole of an ideal gas at 25oC.
a. Calculate q, w, ΔE, ΔS, ΔH, and ΔG for the expansion of this gas isothermally and irreversibly from 2.45 × 10-2 atm to 2.45 × 10-3 atm in one step.
b. Calculate q, w, ΔE, ΔS, ΔH, and ΔG for the same change of pressure as in part a but performed isothermally and reversibly.
c. Calculate q, w, ΔE, ΔS, ΔH, and DG for the one- step isothermal, irreversible compression of 1.00 mole of an ideal gas at 25oC from 2.45 × 10-3 atm to 2.45 × 10-2 atm.
d. Construct the PV diagrams for the processes described in parts a, b, and c.
e. Calculate the entropy change in the surroundings for the processes described in parts a, b and c.
