A system changes from state X to Y with ...

A system changes from state X to Y with a change in internal energy measuring to `"25 kJ mol"^(-1)`, by a reversible path and returns from Y to X by an irreversible path. What will be the net change in internal energy?

A

25 kJ

B

gt 25 kJ

C

lt 25 kJ

D

zero

Text Solution

Verified by Experts

The correct Answer is:
D
For a cyclic process, net change in internal energy is zero. Change in internal energy does not depend on the path by which final stage is reached.
