Chemical Thermodynamics Question 34
Question: Following data is known about melting of a compound AB. $ \Delta H=9.2,kJ,mo{{l}^{-1}} $ , $ \Delta S=0.008,kJ,{{K}^{-1}}mo{{l}^{-1}} $ . Its melting point is [Pb. PMT 2000; AIIMS 2000]
Options:
A) 736 K
B) 1050 K
C) $ 1150,K $
D) $ 1150^{o}C $
Show Answer
Answer:
Correct Answer: C
Solution:
$ T_{m}=\frac{\Delta {H_{fusion}}}{\Delta {S_{fusion}}}=\frac{9.2}{0.008}=1150,K $ .
