$\mathop {\lim }\limits_{{X_A} \to 0} \left ( \frac{P_B^0}{X_B} \right )$ and $\mathop {\lim }\limits_{{X_B} \to 0}\left ( \frac{P_A^0}{X_A} \right )$ are
$C{O_{\left( g \right)}} + \frac{1}{2}{O_{2\left( g \right)}} \to C{O_{2\left( g \right)}}\,;\,\Delta H = - 300\,kJ$
${H_2}_{\left( g \right)} + \frac{1}{2}{O_2}_{\left( g \right)} \to {H_2}{O_{\left( g \right)}}\,;\,\Delta H = - 250\,kJ$
$C_{(s)} + O_{2(g)} \to CO_{2(g)} ; \Delta H = -x\, kJ$
The value of $x$ will be
