Question
**Equilibrium Constant Expression for a Reaction**

To write the equilibrium constant expression, \( K_c \), for the reaction given below, follow these steps:

### Reaction:
\[ \text{NH}_3(g) + \text{HI}(g) \rightarrow \text{NH}_4\text{I}(s) \]

### Instructions:
- Enter the compounds in the order provided in the reaction.
- If either the numerator or the denominator is 1, please enter 1.

### Equilibrium Constant Expression:
- \( K_c = \text{[Products] / [Reactants]} \)
- Since \(\text{NH}_4\text{I}\) is a solid, it is not included in the \( K_c \) expression.

### Input Fields:
- **Reactants:**
  - \( \text{NH}_3 \)
  - \( \text{HI} \)

### Submit Your Answer:
- Use the provided input boxes to submit your calculated \( K_c \) value.
- Click "Submit Answer" to check your submission.
- There are 9 more group attempts remaining.

**Note:** Solids and pure liquids are not included in the equilibrium constant expression. Enter '1' if applicable.

Expert Solution
Step 1: Define equilibrium constant

The equilibrium constant(Kc) is the ratio of the equilibrium concentrations of the products to the reactants raised to the power of their coefficients as in the balanced equation.
