Chemical Thermodynamics Question 273
Question: Which of the following compounds will absorb the maximum quantity of heat when dissolved in the same amount of water - The heats of solution of these compounds at $ 25^{o}C $ in kJ/mole of each solute is given in brackets [AMU (Engg.) 2000]
Options:
A) $ HNO_3(\Delta H=-33) $
B) $ KCl(\Delta H=+17.64) $
C) $ NH_4NO_3,(\Delta H=+25.5) $
D) $ HCl,(\Delta H=-74.1) $
Show Answer
Answer:
Correct Answer: C
Solution:
More +ve is $ \Delta H_{s} $ more is heat of solution.
