Question Consider the following statements.
I. When the system returns to its original condition, the overall change in a state function is zero.
II. When a gas expands, work energy is released, hence work done is negative and is done by the system.
III. \( \mathrm{C}(\mathrm{s})+\mathrm{CO}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{CO}(\mathrm{g}) \).
In this \( \Delta \mathrm{n}_{\mathrm{g}}= \) zero, hence no work is done.
Select the correct statements
(A) I, II and III
(B) I and II
(C) II and III
(D) I and III📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
