Question

NH4Cl(s) xrightarrowNH3(g)+HCl(g) When the above reaction occurs, the entropy (A) remains same (B) decreases (C) increases (D) none of these

Key Idea: The entropy is measurement of randomness. Gases have highest entropy because they have maximum randomness as compared to liquid and gaseous state. NH4Cl(s) xrightarrowNH3(g)+HCl(g) ∵ The reactants are in solid state and products formed are in gaseous state. ∴ Entropy of system increases.
