What would be the heat released when an aqueous solutions containing 0.5 mole of ` HNO_3` is mixed with 0.3 mole of ` OH^(-)` (enthalpy of neutralization is -57.1 kJ)

A

`-28.5 kJ`

B

`-17.1 kJ`

C

` -45.7 kJ`

D

`-1.7 kJ`

Text Solution

Verified by Experts

The correct Answer is:
B
`0.3` mole OH ion will be completely neutralised,` therefore Delta H =- 57. 1 xx 0.3 =- 17.13 kJ`
