Question

Calculate the heat of formation of acetic acid from the following data:
${C H}_{3} C O O H (l) + 2 O_{2} (g) \to 2 {C O}_{2} + 2 H_{2} O (l) . . . . (i) (Δ H = - 2079 k c a l)$
$C (s) + O_{2} (g) \to {C O}_{2} (g); (Δ H = - 94.48 k c a l) . . . (i i)$
$H_{2} (g) + \frac{1}{2} O_{2} (g) \to H_{2} O (l); (Δ H = - 68.4 k c a l) . . . . (i i i)$
