Which of the following are not state functions?
(I)
(II)
(III)
(IV)
Options
- A(I) and (IV)
- B(II), (III) and (IV)
- C(I,) (II) and (III)
- D(II) and (III)
Correct answer
D. (II) and (III)
Step-by-step solution
Key Idea : State function is the property of the system whose value depends only on the initial and final state of the system and is independent of the path.
Internal energy
It is a state function because it is independent of the path. It is an extensive property.
Gibbs energy
It is also a state function because it is independent of the path. It is also an extensive property.
Heat and work are not state functions being path dependent.
