There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. In
Scorpion4ik [409]

Answer:

The net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide is -470.4 kJ/mol.

Explanation:

Step 1 : Calcium carbide and water react to form acetylene and calcium hydroxide

CaC_2(s)+2H_2O(g)\rightarrow

             C_2H_2(g)+Ca(OH)_2(s),\Delta H_1=-414 kJ..[1]

Step 2 : Acetylene, carbon dioxide and water react to form acrylic acid

6C_2H_2(g)+3CO_2(g)+4H_2O(g)\rightarrow 5CH_2CHCOOH(g),\Delta H_2=132 kJ..[2]

Using Hess's law:

[1] × 6 + [2]

6CaC_2(s)+16H_2O(g)+3CO_2\rightarrow 5CH_2CHCOOH(g)+6Ca(OH)_2(s),\Delta H_3=?

\Delta H_3=6\times \Delta H_1+\Delta H_2

\Delta H_3=6\times (-414 kJ)+132 kJ=-2352 kJ

The energy released on formation of 5 moles of acrylic acid = -2352 kJ

The energy released on formation of 1 moles of acrylic acid :

=\frac{-2352 kJ}{5 mol}=-470.4 kJ/mol

Hence, the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide is -470.4 kJ/mol.
