Question

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 net change in internal energy?

Prashant Kotian · Accepted Answer

Correct answer: D. Internal energy U is a state function. For any cyclic process (going from A to B and returning back to A), the net change in internal energy (Δ U) is always zero, regardless of the path being reversible or irreversible.
