Solution

The correct option is B 11.4 kJ
0.2 moles of $H N O_{3}$ will be neutralized with 0.2 moles of KOH. 0.3 moles of $H N O_{3}$ will remain unneutralized.
The heat of neutralisation of a strong acid and a strong alkali is 57.0 kJ /mol.
When 0.2 moles of $H N O_{3}$ is neutralized with 0.2 moles of KOH, the heat of neutralisation is

$0.2 m o l \times 57.0 k J / m o l = 11.4 k J$
