Enthalpy of neutralisation of NaOH with H₂SO₄ is − 57.3 KJ mole⁻¹ and − 55.2 KJ mol⁻¹ with ethanoic acid. Which of the following is the best explanation of this difference -
A
Ethanoic acid is a weak acid and thus requires less NaOH for neutralisation
B
Ethanoic acid is only partly ionised, neutralisation is therefore incomplete
C
Ethanoic acid is monobasic while H₂SO₄ is di-basic
D
Some heat is used to ionized ethanoic acid completely
