The internal energy change when a system goes from state A to B is 40 kJ/mol. If the system goes from A to B by a reversible path and returns to state A by an irreversible path. What would be the change in internal energy?

(a) 40 kJ                                    (b) >40 kJ

(c) <40 kJ                                  (d) Zero
