Write a balanced chemical equation for the standard formation reaction of liquid acetic acid hch3co2.
Afina-wow [57]

The balanced chemical equation for the standard formation reaction of liquid acetic acid is given as ,

2C(gr) +2H_{2} (g) +O_{2} (g)  → CH_{3} COOH(l)

The reaction that form the products from their elements in their standard state is called formation of reaction .The acetic acid consist C , H , and O , So, determine their standard state . Carbon is graphite at 25°C and 1 atm , whereas hydrogen and oxygen are diatomic gases . Hence , we start with unbalanced reaction.

C(gr) +H_{2} (g) +O_{2} (g) → CH_{3} COOH(l)

The balanced chemical equation for the standard formation reaction of liquid acetic acid as,

2C(gr) +2H_{2} (g) +O_{2} (g)  → CH_{3} COOH(l)

The combustion of liquid acetic acid is given as,

CH_{3} COOH(l) + 2O(g) → 2CO_{2}((g) +2H_{2} O(l)                    ΔH =-873
