There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. In

kodGreya [7K]

Answer: The net chemical equation for the production of acrylic acid is given below.

Explanation:

We are given two intermediate equations:

Equation 1: $CaC_2(s)+2H_2O(g)\rightarrow C_2H_2(g)+Ca(OH)_2(s)$

Equation 2: $6C_2H_2(g)+3CO_2(g)+4H_2O(g)\rightarrow 5CH_2CHCO_2H(g)$

To get the net chemical equation for the formation of acrylic acid from calcium carbide, carbon dioxide and water, we multiply the first equation by a factor of '6'.

The equation becomes:

Equation 1: $6C_2H_2(g)+6Ca(OH)_2(s)$

Equation 2: $6C_2H_2(g)+3CO_2(g)+4H_2O(g)\rightarrow 5CH_2CHCO_2H(g)$

Net chemical equation now becomes:

$6CaC_2(s)+16H_2O(g)+3CO_2(g)\rightarrow 5CH_2CHCO_2H(g)+Ca(OH)_2(s)$

Hence, the net chemical equation for the production of acrylic acid is given above.
