Define standard heat of formation. Calculate the heat of formation of acetic acid from the following data :
\( \text{C}(s) + \text{O}_2(g) \rightarrow \text{CO}_2(g)\text{ ; }\Delta H = -99\text{ kcal/mol} \)
\( \text{H}_2(g) + \frac{1}{2}\text{O}_2(g) \rightarrow \text{H}_2\text{O}(l)\text{ ; }\Delta H = -68\text{ kcal/mol} \)
\( \text{CH}_3\text{COOH} + 2\text{O}_2(g) \rightarrow 2\text{CO}_2(g) + 2\text{H}_2\text{O}(l)\text{ ; }\Delta H = -208\text{ kcal/mol} \)
