Answer 2

¤ Equilibrium constant is the ratio of the product of the concentrations of the products raised to their corresponding stoichiometric coefficients to that of the reactants. 

¤ Solids and liquids have constant of 1.
¤ In this case,Kc would always have to be greater than 1.

1. CaCO3(s) ⇌  CaO(s) + CO2(g)

Kc=[CaO][CO2] / [CaCO3].....(Solid=1)
K =CO2

2. CH3COOC2H5(aq) + H2O(l) ⇌CH3COOH (aq) + C2H5OH (aq )

Kc=[CH3COOH(aq)][C2H5OH (aq) ] / [CH3COOC2H(aq)][H2O (l) ]

Kc=[CH3COOH(aq)][C2H5OH (aq) ] / [CH3COOC2H5]
