11. 已知下列的熱反應式

$\mathrm{H}_{2(\mathrm{g})} + \mathrm{F}_{2(\mathrm{g})} \rightarrow 2 \mathrm{HF}_{(\mathrm{g})}$ $\Delta H = -537 \mathrm{~kJ}$

$\mathrm{C}_{(s)} + 2 \mathrm{~F}_{2(\mathrm{g})} \rightarrow \mathrm{CF}_{4(\mathrm{g})}$ $\Delta H = -680 \mathrm{~kJ}$

$2 \mathrm{C}_{(s)} + 2 \mathrm{H}_{2(g)} \rightarrow \mathrm{C}_{2} \mathrm{H}_{4(g)}$ $\Delta H = 52 \mathrm{~kJ}$

估算下列反應的反應熱 $(\Delta H)$ 是多少？

$\mathrm{C}_{2} \mathrm{H}_{4(g)} + 6 \mathrm{~F}_{2(g)} \rightarrow 2 \mathrm{CF}_{4(g)} + 4 \mathrm{HF}_{(g)}$
(A) $-2486 \mathrm{~kJ}$
(B) $-2382 \mathrm{~kJ}$
(C) $-1165 \mathrm{~kJ}$
(D) $91 \mathrm{~kJ}$
(E) $446 \mathrm{~kJ}$
