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 retums to state A by an irreversible path what would be the net change in internalenergy?

Options

  1. A>40 ~kJ
  2. B< 40 ~kJ
  3. CZero
  4. D40 ~kJ

Correct answer

C. Zero

Step-by-step solution

For a cyclic process the net change in the internal energy is zero because the change in internal energy does not depend on the path.
