    What would be the amount of heat released when an aqueous solution containing 0.5 mole of HNOs is mixed with 0.3 mole of OHT (enthalpy of neutralisation is -57.1 kJ)?

    A) 28.5 kJ             

    B) 17.1 kJ

    C) 45.7 kJ             

    D) 1.7 kJ

    Correct Answer: B

    Solution :

    \[0.3\text{ }mole\text{ }O{{H}^{-}}\text{ }neutralise\text{ }0.3\text{ }mol\text{ }HN{{O}_{3}}\] \[\Delta H=-57.1\times 0.3=-17.13\text{ }kJ\]
