 equation describing heterogeneous reactions Choose the appropriate equilibrium expression for each

a. 2Na2O2(s) + 2CO2(g)  2Na2CO3(s) + O2(g)b. SiO2(s) + 4HF(g)  SiF4(g) + 2H2O(g)

c. CaCO3(s)  CaO(s) + CO2(g)

d. 2NaHCO3(s)  Na2CO3(s) + CO2(g) + H2O(g)

a. K = [O2]^2 / [CO2]^2  (do not include solids)

b. K = [SiF2] [H2O]^2 / [HF]^4

c. K = [CO2]

d. [CO2][H2O]
