Which equation shows the standard enthalpy change of formation of ethanol, $\text{C}_2\text{H}_5\text{OH}$?
- A$2C(g) + 3H_2(g) + \frac{1}{2}O_2(g) \rightarrow C_2H_5OH(l)$
- B$2C(s) + 3H_2(g) + \frac{1}{2}O_2(g) \rightarrow C_2H_5OH(l)$
- C$2C(s) + 3H_2(g) + \frac{1}{2}O_2(g) \rightarrow C_2H_5OH(g)$
- D$2C(g) + 6H(g) + O(g) \rightarrow C_2H_5OH(l)$
