The following two reactions are known
\[
\begin{array}{l}
\mathrm{Fe}_{2} \mathrm{O}_{3(s)}+3 \mathrm{CO}_{(g)} \rightarrow 2 \mathrm{Fe}_{(s)}+3 \mathrm{CO}_{2(g)} ; \Delta H=-26.8 \mathrm{~kJ} \\
\mathrm{FeO}_{(s)}+\mathrm{CO}_{(g)} \rightarrow \mathrm{Fe}_{(s)}+\mathrm{CO}_{2(g)} ; \Delta H=-16.5 \mathrm{~kJ}
\end{array}
\]
\( \mathrm{P} \)
The value of \( \Delta H \) for the following reaction
W \( \mathrm{Fe}_{2} \mathrm{O}_{3(s)}+\mathrm{CO}_{(g)} \rightarrow 2 \mathrm{FeO}_{(s)}+\mathrm{CO}_{2(g)} \) is
(a) \( +10.3 \mathrm{~kJ} \)
(b) \( -43.3 \mathrm{~kJ} \)
(c) \( -10.3 \mathrm{~kJ} \)
(d) \( +6.2 \mathrm{~kJ} \)
