Chemical Thermodynamics Question 289
Question: When the aqueous solution of 0.5 mole $ HNO_3 $ is mixed with the 0.3 mole of $ O{{H}^{-}} $ solution, then what will be the liberated heat (Enthalpy of neutralization is = 57.1 kJ) [Kerala CET 2005]
Options:
A) 28.5 kJ
B) 17.1 kJ
C) 45.7 kJ
D) 1.7 kJ
E) 2.85 kJ
Show Answer
Answer:
Correct Answer: B
Solution:
0.3 mole $ O{{H}^{-}} $ , neutralize 0.3 mole of $ HNO_3 $ Evolved heat, $ =57.1\times 0.3=17.13kJ $
