Question

1)which energy involved in neutralisation reaction
2) and what type of chemical reaction in neutralisation reaction ​

Answer 1

1.) The heat (or enthalpy) of neutralization (ΔH) is the heat evolved when an acid and a base react to form a salt plus water. Q in the above equation is -ΔH and is expressed in kJ/mol of water. Neutralization reactions are generally exothermic and thus ΔH is negative.

2.) neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
