Equal volumes of molar HCl and H₂SO₄ are neutralised by dilute NaOH solution and xK.cal and yK.cal of heat are liberated respecitvely. Which of the following is true?

Heat released when 1 equivalent of acid is neutralized by 1 equivalent of base is known as heat of neutralization.

1 mole of HCl = 1 equivalent of HCl

1 mole of H₂SO₄ = 2 equivalent of H₂SO₄

Heat released when equal volumes of 1M NaOH is neutralized by 1M HCl = $∆\mathrm{H}$=X Kcal

Heat released when equal volumes of 1M NaOH is neutralized by 1M H₂SO₄ = $∆\mathrm{H}$=2X Kcal

Given 2X Kcal = y; X=$\frac{\mathrm{y}}{2}$
