Given below are two statements : Statement I : A process is said to be reversible, if a change is brought out in such a way that the process could, at any moment, be reversed by an infinitesimal change. Statement II : A reversible process proceeds by a series of equilibrium states such that system and surroundings are near equilibrium with each other. In the light of the above statements, choose the most appropriate

Options

  1. ABoth statement I and statement II are incorrect.
  2. BStatement I is correct but statement II is incorrect
  3. CStatement I is incorrect but statement II is correct.
  4. DBoth statements I and statements II are correct.

Correct answer

D. Both statements I and statements II are correct.

Step-by-step solution

Both statements are correct for the following reasons: - Statement I: A process is said to be reversible if it can be reversed by an infinitesimal (very small) change in the external conditions. This means that the system can return to its initial state without leaving any change in the system or surroundings, which is a key feature of a reversible process. - Statement II: A reversible process proceeds through a series of equilibrium states, meaning that at every point, the system and surroundings are nearly in equ
