1.	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?A. `40 kJ`B. ` gt 40 kJ`C. ` lt 40 kJ`D. zero
Answer» Correct Answer - D Change in internal energy is a state function `:. DeltaU(AtoB)=40 kJ mol^(-1)` `DeltaU(BtoA)=-40 kJ mol^(-1)` `:. ` Net change in internal energy `=` Zero.
