**Kinetics and Equilibrium: Writing the Concentration Equilibrium Expression for a Reaction**

**Task:**
Write the concentration equilibrium constant expression for this reaction:

\[ \text{CH}_3\text{CO}_2\text{H}_{(aq)} + \text{C}_2\text{H}_5\text{OH}_{(aq)} \rightarrow \text{CH}_3\text{CO}_2\text{C}_2\text{H}_5_{(aq)} + \text{H}_2\text{O}_{(l)} \]

**Instructions:**
In the text box provided, enter the equilibrium expression based on the reaction above. Note that for heterogeneous equilibria involving water as a liquid, the concentration of water is not included in the equilibrium expression.

**Tools:** 
- A box for inputting the equilibrium expression.
- Buttons for formatting or clearing the expression.

### Key Points
- Identify the reactants and products in aqueous form.
- Exclude the liquid water from the expression.
- Use proper equilibrium expression format based on the law of mass action.

Expert Solution
Step 1: Equilibrium constant (Kc) expression,

Equilibrium constant expression for any reaction is,

yReactant(aq) ----> xProduct(aq)

K = [Products]x/[Reactants]y

Note: pure solid and pure liquid not included in the equilibrium constant expression.
