marin [14]

Answer:

THE EQUILIBRIUM CONSTANT EXPRESSION Kc = \frac{[C2H5OH]}{[C2H5OC2H5]}

Explanation:

The equilibrium constant, Kc is an expression given by the ratio of the concentrations of the products over the reactants. TN.B: the activities of pure solids and liquids are equal to 1.

Kc = \frac{[products]^n}{[reactants]^n} where n= no of moles

Reaction equation:

2C2H5OH  \frac{conc H2SO4, 140^o}{}→ C2H5OC2H5

⇒ Kc = \frac{[C2H5OC2H5] [H2)]}{[C2H5OH]^2} but [H20] = 1

∴ Kc = \frac{[C2H5OH]}{[C2H5OC2H5]}
