When equal volume of $\displaystyle 1$ M HCl and $\displaystyle 1 \mathrm{M} \mathrm{H}_2 \mathrm{SO}_4$ are separately neutralised by excess volume of $\displaystyle 1$ M NaOH solution. $\displaystyle x$ and $\displaystyle y \mathrm{~kJ}$ of heat is liberated respectively. The value of $\displaystyle y / x$ is $\displaystyle \_\_\_\_$.
