Thermodynamics And Thermochemistry Result Question 12

The $\Delta H_f^{\circ}$ for $\mathrm{CO}_2(g), \mathrm{CO}(g)$ and $\mathrm{H}_2 \mathrm{O}(g)$ are $-393.5,-110.5$ and $-241.8 \mathrm{~kJ} \mathrm{~mol}^{-1}$ respectively. The standard enthalpy change (in $\mathrm{kJ} $ $\mathrm{mol}^{-1}$ ) for the reaction $\mathrm{CO}_2(g)+\mathrm{H}_2(g) \longrightarrow \mathrm{CO}(g)+\mathrm{H}_2 \mathrm{O}(g)$ is

(a) $524.1$

(b) $+41.2$

(c) $-262.5$

(d) $-41.2$
