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

A

57.0kJ

B

11.4 kJ

C

28.5 kJ

D

34.9kJ

Text Solution

Verified by Experts

The correct Answer is:
B
0.2 mole will neutralize 0.2 mole of `HNO_(3)`, heat evolved `=57 xx 0.2 = 11.4`kJ
