$\mathrm{C}\mathrm{H}_{3} -\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{O}-\mathrm{C}\left(\mathrm{CH}_{3}\right)_{3} \xrightarrow[\Delta]{{\mathrm{excess} \mathrm{HI}}} \mathrm{C}+\mathrm{D}$
[At $45^{\circ} \mathrm{C}$ vapour pressure of benzene is $280\, \mathrm{~mm} \,\mathrm{Hg}$ and that of octane is $420\, \mathrm{~mm} \,\mathrm{Hg}$. Assume Ideal gas]
${H_2}O(g) + C(s) \to CO(g) + {H_2}(g);\,\Delta H = 131\,kJ$$CO(g) + \frac{1}{2}{O_2}(g) \to C{O_2}(g);\Delta H = - 282\,kJ$
${H_2}(g) + \frac{1}{2}{O_2}(g) \to {H_2}O(g);\,\Delta H = - 242\,kJ$
$C(s) + {O_2}(g) \to C{O_2}(g);\,\Delta H = X\,kJ$ The value of $X$ is ......$kJ$
