So write the Keq expression, substitute the concentrations given and solve for the concn of H2O.
Post your work if you get stuck.
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
