Define heat of formation. Calculate the heat of formation of acetic acid from the following data:
\( C(s) + O_2(g) \rightarrow CO_2(g), \Delta H = -99 \ Kcal/mol \)
\( H_2(g) + \frac{1}{2}O_2(g) \rightarrow H_2O(l), \Delta H = -68 \ Kcal/mol \)
\( CH_3COOH(l) + 2O_2(g) \rightarrow CO_2(g) + H_2O(l), \Delta H = -208 \ Kcal/mol \)
