Kc is defined as concentration of product by concentration of reactant with each concentration term raised to power that is equal to its stoichiometric coefficient in balanced equation
pure liquid and solid do not appear in Kc
a)
NH4Cl is solid and hence will not appear in Kc expression
Kc = [NH3][HCl]
b)
C is solid and hence will not appear in Kc expression
Kc = [CO2][N2]^2 / [N2O]^2
c)
Na2CO3, H2O and NaHCO3 will not appear in Kc expression
Kc = 1/[CO2]
d)
Fe(OH)3 is solid and hence will not appear in Kc expression
Kc = 1/[Fe3+][OH-]^3
