The reaction between ethyl acetate and water attains a state of equilibrium in an open vessel, but not the decomposition of CaCO3. Explain.
CH2 COOC2H5 (l) + H2O (l) ⇌ CH3COOH (l) + C2H5OH (l) Here both reactants and products are liquids and they will not escape from the vessel even if it is open. Therefore equilibrium is attained. CaSO3 (s) ⇌ CaO (s) + CO2 (g) Here CO2 is a gas. It will escape from the vessel if it is open and so backward reaction cannot take place. Therefore equilibrium is attained.
