Question
**Equilibrium Concentration Calculation**

Consider the following reaction, equilibrium concentrations, and equilibrium constant at a particular temperature. Determine the equilibrium concentration of \( \text{H}_2\text{O(g)} \).

\[
\text{C}_2\text{H}_4\text{(g)} + \text{H}_2\text{O(g)} \rightleftharpoons \text{C}_2\text{H}_5\text{OH(g)} \quad K_c = 9.0 \times 10^3
\]

- \([\text{C}_2\text{H}_4]_{\text{eq}} = 0.015 \, \text{M}\)
- \([\text{C}_2\text{H}_5\text{OH}]_{\text{eq}} = 1.69 \, \text{M}\)

**Objective**: Determine the equilibrium concentration of \([\text{H}_2\text{O}]_{\text{eq}}\).

Note that the balanced chemical equation indicates that for every mole of \(\text{C}_2\text{H}_4\) reacted, one mole of \(\text{H}_2\text{O}\) is also reacted to produce one mole of \(\text{C}_2\text{H}_5\text{OH}\). Use \(K_c\) and the given equilibrium concentrations of \(\text{C}_2\text{H}_4\) and \(\text{C}_2\text{H}_5\text{OH}\) to solve for \([\text{H}_2\text{O}]_{\text{eq}}\).
