Question

The following two reactions are known

Fe₂O_3(s) + 3CO_(g) $ \to $ 2Fe_(s) + 3CO_2(g); $\Delta $H = $-$ 26.8 kJ

FeO_(s) + CO(g) $ \to $ Fe_(s) + CO_2(g); $\Delta $H = $-$ 16.5 kJ

The value of $\Delta $H for the following reaction

Fe₂O_3(s) + CO_(g) $ \to $ 2FeO_(s) + CO_2(g) is

+ 10.3 kJ

$-$ 43.3 kJ

$-$ 10.3 kJ

+ 6.2 kJ
