    Enthalpy of neutralisation of \[HCl\] with \[NaOH\] is x. The heat evolved when \[500\text{ }mL\] of \[2\text{ }N\text{ }HCl\] are mixed with \[250\text{ }mL\] of \[4N\text{ }NaOH\] will be.

    A) \[500x\]            

    B) \[100x\]

    C) \[x\]                                 

    D) \[~10x\]

    Correct Answer: C

    Solution :

    [c] Enthalpy of neutralisation of \[HCl\] with \[NaOH\] is x. In question gev of \[HCl\] \[\left( \frac{500\times 2}{1000}=1gev \right)\,and\,NaOH\left( \frac{250\times 4}{1000}=1gev \right)\] hence the value x.
