$<b>Hello Friend<b>$ ❤️❤️

The answer of u r question is...✌️✌️

Ans:✍️✍️✍️✍️✍️✍️✍️✍️✍️✍️

According to the definition Equilibrium constant is the ratio of products.

Equation.

C2H5OH+CH3COOH+-->CH3COOC2H5+H2O

In the above equation.

☺️ Coefficient are 1

☺️ Exponential are discarded

☺️1 mole of water is formed.

KC=2/3×2/3

=4/9

=0.44

Hope it helps uu buddy!!❤️❤️

Thank you.. ☺️☺️

Answer






According to the definition Equilibrium constant is the ratio of products.


C2H5OH+CH3COOH+-->CH3COOC2H5+H2O





So , VALUE OF KC IS


KC = fraction of [H2O]×[CH3COOC2H5][CH3COOH]×[C2H5OH]

KC=2/3 ×2/3
= 4 / 9





hope it helps
