Consider the following reaction, equilibrium concentrations, and equilibrium constant at a particular temperature. Determine the equilibrium concentration of H2O (g). C2H4 (g) + H2O (g) ⇌ C2H5OH (g) Kc = 9.0 * 103 [C2H4]eq = 0.015 M [C2H5OH]eq = 1.69 M

Kc = [C2H5OH]/{[C2H4][H2O]}

[H2O] = [C2H5OH]/{[C2H4] x Kc}

[H2O] = 1.69 / (0.015 x 9.0 x 10^3) = 0.013 M

Explanation:

Kc is the equilibrium constant, it is egal to the product of the equilibrium concentration of the product dived by the product of the equilibrium concentration of the reactants.

with that formula and what is given, male the equilibrium concentration of H2O the subject of the formula and calculate its concentration by substituting given values.
