[" 8.Reaction between methanol and formic acid attains a state of equilibrium in an open "],[" vessel but decomposition of "NH_(4)Cl" does not.Why? "]

Reaction between ethyl acetate and water attains a state of equilibrium in an open vessel but not the decomposition of CaCO_(3). Explain.

The reaction between ethanoic acid and ethanol is reversible even in an open vessel.Why?

Can liquid hArr gas equilibrium be attained in an open vessel ? If not why?

Why is an aqueous solution of NH_4Cl acidic ?

Write the expression for equilibrium constant for the decomposition of NH_4Cl by the reaction. NH_4Cl gives NH_3+HCl

When 1 mole of N_2 and 1 mole of H_2 is enclosed in a 5 L vessel and reaction is allowed to attain equilibrium . It is found that at equilibrium there is x mole of H_2 . The number of moles of NH_(3) formed would be
