13) Calcule a entalpia de formação do fenol

13. Calcule a entalpia de formação do fenol $(\mathrm{C6H} 5 \mathrm{OH}$ ), segundo a equação: $\mathrm{C} 6 \mathrm{H} 5 \mathrm{OH}(\mathrm{l})+7 \mathrm{O} 2(\mathrm{~g}) \rightarrow 6 \mathrm{CO} 2(\mathrm{~g})+3 \mathrm{H} 2 \mathrm{O}(\mathrm{g}) \Delta \mathrm{H}=-3054 \mathrm{KJ} / \mathrm{mol}$ Sabendo que as entalpias de formação do $\mathrm{CO} 2(\mathrm{~g})$ e $\mathrm{H} 2 \mathrm{O}(\mathrm{g})$ valem, respectivamente: $-395 \mathrm{~kJ} / \mathrm{mol} \mathrm{e}-286 \mathrm{~kJ} / \mathrm{mol}$ a $25^{\circ} \mathrm{C}$ e $1 \mathrm{~atm}$. a) $-174,0 \mathrm{~kJ} / \mathrm{mol}$ b) $-2373,0 \mathrm{~kJ} / \mathrm{mol}$ c) $+174,0 \mathrm{~kJ} / \mathrm{mol}$ d) $+2373,0 \mathrm{~kJ} / \mathrm{mol}$
