The internal energy change when a system goes fromk state `A` to `B` is `40 kJ mol^(-1)`. 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?

Options

A. `gt 40` kJ
B. ` lt 40` kJ
C. Zero
D. 40 kJ

Answer

C

Explanation

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