The heat of neutralisation of a strong acid and a strong alkali is 57.0 kJ mol^(-1). The heat released when 0.5 mole of HNO_(3) solution is mixed with 0.2 mole o KOH is

Answer»

57.0 kJ
11.4 kJ
28.5 kJ
34.9 kJ

Solution :0.2 mole of KOH will NEUTRALISE 0.5 mole of `HNO_(3)`
`THEREFORE`HEAT evolved`=57xx0.2=11.4kJ`
