Question

If different quantities of ethyl alcohol and acetic acid are used in the reversible reaction $C{H}_{3}COOH+C_2{H}_{5}OH\iff C{H}_{3}COO{C}_2{H}_5+H_{2}O$
then the equilibrium constant will have the values:

• A. same in all cases
• B. different in all cases
• C. higher in cases when higher concentration of ethyl alcohol is used
• D. higher in cases when higher concentration of acetic acid is used

Answer 1

Answer: (A)

same in all cases

The magnitude of the equilibrium constant is not affected by the changes in concentrations of reactants and products, pressure and volume. Thus when different quantities of ethyl alcohol and acetic acid are used in the reaction, the value of the equilibrium constant remains same.
