Chemical Thermodynamics Question 369
Question: Enthalpy of neutralisation of $ HCl $ with $ NaOH $ is x. The heat evolved when $ 500mL $ of $ 2NHCl $ are mixed with $ 250mL $ of $ 4NNaOH $ will be.
Options:
A) $ 500x $
B) $ 100x $
C) $ x $
D) $ ~10x $
Show Answer
Answer:
Correct Answer: C
Solution:
- Enthalpy of neutralisation of $ HCl $ with $ NaOH $ is x. In question gev of $ HCl $
$ ( \frac{500\times 2}{1000}=1gev ),and,NaOH( \frac{250\times 4}{1000}=1gev ) $ hence the value x.
