AIPMT PRELIMS 2000 Chemistry Entropy MCQ Question
Type: MCQ-numerical-Medium-Class 11
At 27°C latent heat of fusion of a compound is 2930 J/mol. Entropy change is :
A
9.77 J/mol–K
B
10.77 J/mol–K
C
9.07 J/mol–K
D
0.977 J/mol–K
Correct Answer
Option A
Detailed Explanation
The entropy change ΔS = ΔH/T, where ΔH = 2930 J/mol and T = 300 K (27°C). ΔS = 9.77 J/mol–K.
