Assertion:The enthalpies of neutralised ...

Assertion:The enthalpies of neutralised of strong acids and strong bases are always same.
Reason:Neutralisation is heat of formation of water.

A

If both ther assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both the assertion and reason are true but reason is not the correct explantion of the assertion.

C

If the assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
The enthalpies of neutralisation of strong acids and strong bases are the same they are `13.7Kcal` . The reason is that it is heat of formation of water from `H^(+)` and `OH^(-)` ions.
`H^(+)+OH^(-)rarrH_(2)O,DeltaH=13.7Kcal` . Thus, both assertion and reason are true.
