Assertion (A): The Heat of ionisation of water is equal to the heat of neutralistion of a strong acid with a strong base.
Reason (R ) : Water ionises to a very small extent while `H^(o+)` ions from from an acid combine very rapidly with `overset(Theta)OH` from a base to form `H_(2)O`.

A

If both (A) and (R) are correct and (R) is the correct reason for (A).

B

If both (A) and (R) are correct but (R) is not the correct explanation for (A).

C

If (A) is true but (R) is false

D

If both (A) and (R) are false.

The heat of neutralisation for strong acid and strong base forming 2 moles of water is

The enthalpy of formation of H_(2)O(l) is -280.70 kJ/mol and enthalpy of neutralisation of a strong acid and strong base is -56.70 kJ/mol. What is the enthalpy of formation of OH^(-) ions?

Assertion(A) : The value of enthalpy of neutralization of a weak acid by strong base is numerically less than 57.1 kJ . Reason(R ) : All OH^(-) ions of strong base are not completely neutralized by H^(+) ions obtained from acid.

Assertion : Heat of neutralisation of nitric acid with NaOH is same to that of HCl and NaOH. Reason : In both cases strong acid and strong bases are neutralised. H^(+)+OH^(-)rarrH_(2)O .

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

If water is formed from H^(+) ions and OH^(-) the heat of formation of water is :

Assertion(A) : The value of enthalpy of neutralisation of strong acid and weak base is numerically less than 57.1 kJ . Reason(R ) : All the H^(+) ions furnished by 1g equivalent of a strong acid are not completely neutralized by the OH^(-) ions from the weak base.
