Given below are two statements: Statement I: All natural processes are spontaneous. Statement II: All natural processes are irreversible.

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

- Statement I: All natural processes are spontaneous because they occur without any external intervention. Spontaneity is driven by a tendency toward increased entropy or decreased free energy in a system. - Statement II: All natural processes are irreversible because they proceed in one direction and cannot return to their original state without external work. This aligns with the second law of thermodynamics, which states that entropy increases in irreversible processes.
