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

`11.4KJ`

C

`28.5KJ`

D

`34.9KJ`

Text Solution

Verified by Experts

The correct Answer is:
B

From the given data,
Only `0.2` moles of each of `HNO_(3)` and `KOH` will be neutraalized.
So. 1 mol required `57.0KJ`
`:. 0.2` mol requires `57.0xx0.2KJ`
`=11.4KJ`
