The number of equivalents of H2SO4 is 2

while the number of equivalents of HCl is just 1.


It means that H2SO4 gives 2 moles of H+ ions while HCl only gives 1 mole of H+.

So the energy liberated by H2SO4 will be somewhat equal to twice the energy liberated by HCl.

Therefore, the correct relation between A and B is
2A = B

Hence, option number (2) is correct
