The balanced chemical equation for the standard formation reaction of liquid acetic acid is given as ,
[tex]2C(gr) +2H_{2} (g) +O_{2} (g)[/tex] → [tex]CH_{3} COOH(l)[/tex]
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.
[tex]C(gr) +H_{2} (g) +O_{2} (g)[/tex] → [tex]CH_{3} COOH(l)[/tex]
The balanced chemical equation for the standard formation reaction of liquid acetic acid as,
