Which is/are an irreversible process(es)?
Options:(select one or more)
Answer:
A, C
Solution:
An irreversible process is one that cannot be reversed by infinitesimal changes and proceeds spontaneously in one direction.
(A) Mixing of two gases by diffusion is irreversible because once mixed, they cannot be separated naturally.
(C) Dissolution of NaCl in water is also irreversible under normal conditions as ions disperse randomly.
(B) and (D) occur at equilibrium conditions (373 K, 273 K at 1 atm), so they are reversible.
Hence, correct answer: A and C.
