Aşağıdaki tepkimelerden hangisi $CH_3OH(s)$ bileşiğinin standart molar oluşum entalpisini ($\Delta H_f^\circ$) ifade eder?
A) $CH_3OH(s) \to C(k) + 2H_2(g) + \frac{1}{2}O_2(g)$
B) $C(k) + 2H_2(g) + \frac{1}{2}O_2(g) \to CH_3OH(s)$
C) $CH_4(g) + \frac{1}{2}O_2(g) \to CH_3OH(s)$
D) $C(k) + H_2O(g) + H_2(g) \to CH_3OH(s)$
E) $2C(k) + 4H_2(g) + O_2(g) \to 2CH_3OH(s)$
