The concentrations of HCl an NaOH solutions used in the neutralization reaction are approximately equivalent, yet the volumes of HCl and NaOH solutions used in the reactions are not equal. Explain why.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
