Question

reaction betwren acetic acid and ethyl alcohol attains a state of equilibrium in an open vessel but decompostio of CaCO3 does not .why

Answer 1

Answer:

Explanation:

Decomposition of CaCO3 produces CO2 which is gaseous hence it escapes if reaction is carried out in open vessel, therefore equilibrium can never be attained. Reaction of ethyl alcohol and acetic acid does form any gaseous product hence equilibrium can be achieved even in open vessel.

Answer 2

Formation of Carbon Dioxide Gas

Explanation:

Decomposition of $CaCO_3$ evolves $CO_2$ gas that is escaped out during the reaction carried out in an open vessel. The reaction is as follows -

$CaCO_3$ → $CaO + CO_2$

∴ In this case, an equilibrium can never be achieved or attained.

During the reaction between ethyl alcohol and acetic acid, there is no such formation of any gaseous product like carbon dioxide. The reaction is as follows -

$C_2H_5OH + CH_3COOH$ → $H_2O + CH_3COOC_2H_5$

∴ In this case, an equilibrium can be achieved even the reaction is carried out in an open vessel.
