Which equation correctly represents the standard enthalpy of formation of methanol, \(\Delta H_f^\circ\), under standard conditions?
Select one option.
A
\(\text{CH}_3\text{OH}(l) \rightarrow \text{C}(s,\text{graphite}) + 2\text{H}_2(g) + \tfrac{1}{2}\text{O}_2(g)\)
B
\(\text{C}(s,\text{graphite}) + 2\text{H}_2(g) + \tfrac{1}{2}\text{O}_2(g) \rightarrow \text{CH}_3\text{OH}(l)\)
C
\(\text{CO}(g) + 2\text{H}_2(g) \rightarrow \text{CH}_3\text{OH}(l)\)
D
\(\text{C}(g) + 4\text{H}(g) + \text{O}(g) \rightarrow \text{CH}_3\text{OH}(l)\)
E
\(\text{CH}_3\text{OH}(l) + \tfrac{3}{2}\text{O}_2(g) \rightarrow \text{CO}_2(g) + 2\text{H}_2\text{O}(l)\)
