If $T_1=2 T_2$ and $\left(\Delta G_2^{\Theta}-\Delta G_1^{\varphi}\right)=R T_2 \ln x$, then the value of $x$ is. . . . .
$\left[\Delta G_1^\theta\right.$ and $\Delta G_2^\theta$ are standard Gibb's free energy change for the reaction at temperatures $T_1$ and $T_2$, respectively.]

$Fe_2O_{3(s)} + 3CO_{(g)} \rightarrow 2Fe_{(s)} + 3CO_{2(g)};$ $\Delta H = - 26.8\, kJ$
$FeO_{(s)} + CO_{(g)} \rightarrow Fe_{(s)} + CO_{2(g)} \, ;$ $\Delta H = - 16.5\, kJ$
The value of $\Delta H$ for the following reaction
$Fe_2O_{3(s)} + CO_{(g)} \rightarrow 2FeO_{(s)} + CO_{2(g)}$ is ............. $\mathrm{kJ}$
