Q. Equal volume of 1 M HCl and 1 M $H_{2} S O_{4}$ are neutralized by by dilute NaOH solution and x and y kcal of heat are liberated respectively. Which of the following is true?

x = y

x = 0.5 y

x = 0.4 y

None of these

$1 mole H_{2} SO_{4} = 2 eq . H_{2} SO_{4}$
$1 mole HCl = 1 eq . HCl$
Thus, for equal volumes of two acids to be neutralized separately with NaOH, heat evolved will be twice in case of $H_{2} S O_{4}$ to that of HCl.
