![**Equilibrium Constant Expression for a Chemical Reaction**
To determine the equilibrium constant expression, K, for the given reaction:
\[ \text{HCN (aq)} + \text{H}_2\text{O (l)} \rightleftharpoons \text{H}_3\text{O}^+ \text{(aq)} + \text{CN}^- \text{(aq)} \]
**Instructions:**
- Enter the compounds in the order they appear in the reaction.
- If either the numerator or denominator is blank, enter the value 1.
**Reaction Expression:**
For this reaction, the equilibrium constant expression, K, is written as:
\[ K = \frac{[\text{H}_3\text{O}^+][\text{CN}^-]}{[\text{HCN}]} \]
Since \(\text{H}_2\text{O}\) is a liquid, its concentration is not included in the equilibrium expression.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5e64e050-9cb6-467e-8132-ec94d7497579%2F204b1446-2bbf-4c92-8a79-b90e71527825%2Ftg8a2w_processed.png&w=3840&q=75)
