Question

Find the molar enthalpy of neutralization for H2SO4

Answer 1

The enthalpy of neutralization of H₂SO₄ is in fact the enthalpy of water formation:

H₂SO₄ + 2NaOH $\rightarrow$ Na₂SO₄ + 2H₂O;

OH^- + H⁺ $\rightarrow$ H₂O;

Thus, the molar enthalpy for this reaction is -57.62 kJ/mol at 25 C.
