@ gayathri 
Kc can be defined as the equilibrium constant when one or more than one phase of the reaction will be liquid . 
the kc for the reaction will be 
Kc=  [CH3COOH] * [C2H5OH]  /  [CH3COOC2H5] *[H2O]  
ITS SIMPLE . as u just have to write the ratio of the rate of forward and the backward reaction , that is actually the equilibrium constant . 
which is the concentration oif the product raised to its stochimetry coefficient , divided by the concentration of the reactant with its stoichometry coefficient . 
HOPE IT CLEARS YOUR DOUBT .

but active mass of solid and liquid is 1.then why should we include H2O.IT SHOULD BE EXCLUDED.that is my doubt please clear this
