${A_2}(g)\, + \,{B_2}(g)\,\overset {{K_1}} \leftrightarrows \,2AB(g)\,\,\,......(1)$
$6AB\,(g)\,\,\overset {{K_2}} \leftrightarrows \,\,3{A_2}(g)\, + \,3{B_2}(g)......(2)$
The relation between $K_1$ and $K_2$ is
${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 ......$kJ$
