A) (I) and (IV)
B) (II), (III) and (IV)
C) (I), (II) and (III)
D) (II) and (III)
Correct Answer: D
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. \[\because \]Internal energy \[(\Delta E)=q+W\] It is a state function because it is independent of the path. It is an extensive property. \[\because \]Gibbs energy (G) = H - TS It is also a state function because it is independent of the path. It is also an extensive property. Heat (q) and work (W) are not state functions being path dependent.
