The internal energy change when a system goes from state A to B is 40 kJ/mole. 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 net change in internal energy?

For a cyclic process the net change in the internal energy is zero because the change in internal energy doesnot depend on the path.

zero.

that is because ''change in internal energy'' doesnt depend on the path taken. it just depends on the initial and final state
