Question

For a reaction between strong acid and strong base, the heat of neutralization is?

• A. $14.2kcal/mol$
• B. $-57.1kcal/mol$
• C. $13.6kcal/mol$
• D. $15kcal/mol$

Answer 1

The correct option is B $-57.1kcal/mol$

For a reaction between strong acid and a strong base, heat of neutralization will be negative becuase the reaction is exothermic($\Delta H<0$).

${△}_{neut}{H}^{⊝}=-57.1KJ/mol$
