Question

During which of the following processes, does entropy decrease?

(A) Freezing of water to ice at 0…C

(B) Freezing of water to ice at …10…C

(C) N₂(g) + 3H₂(g) … 2NH₃(g)

(D) Adsorption of CO(g) on lead surface.

(E) Dissolution of NaCl in water

Choose the correct answer from the options given below :

Accepted Answer

Option C. A, B … Freezing of water will decrease entropy as particles will move closer and forces of
