Q. The heat of neutralisation of a strong acid and a strong alkali is 5$7.0\ kJ\ mol^{- 1}$. The heat released when 0.5 mole of $HNO_{3}$ solution is mixed with 0.2 mole of KOH is

A) 57.0 kJ
B) 11.4 kJ
C) 28.5 kJ
D) 34.9 kJ
Explanation

(b)
0.2 mole will neutralize 0.2 mole of $HNO_{3}$ heat evolved $= 51 \times 0.2 = 11.4\$kJ
