Question

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

CaC2 (s) + 2H2O (l) ⇌ C2H2 (g) + Ca(OH)2 (s)	K1

     

6C2H2 (g) + 3CO2 (g) + 4H2O (g) ⇌ 5CH2CHCO2H (g)

K2

The net reaction is:

     

6CaC₂ (s)+16H₂O (l) + 3CO₂ (g)

⇌

6CaOH₂ (s) + 5CH₂CHCO₂H(g)

Write an equation that gives the overall equilibrium constant K in terms of the equilibrium constants

K1

and

K2. If you need to include any physical constants, be sure you use their standard symbols
