### Equilibrium Calculation Exercise

**Reaction:**
\[ \text{SO}_2\text{Cl}_2(\text{g}) \rightleftharpoons \text{SO}_2(\text{g}) + \text{Cl}_2(\text{g}) \]

**Given Parameters:**
- Equilibrium Constant (\( K \)) at 400 K: 0.520
- Reaction Quotient (\( Q \)): \( 2.67 \times 10^{-2} \)
  
**Task:**
Calculate the value of "X" from the "ICE table" based on the initial concentrations.

**Initial Concentrations:**
- \([ \text{SO}_2\text{Cl}_2 ] = 1.50 \, \text{M} \)
- \([ \text{SO}_2 ] = 0.200 \, \text{M} \)
- \([ \text{Cl}_2 ] = 0.200 \, \text{M} \)

\[ \text{"X"} = [ \, ? \, ] \]

**Input Box:**
There is an input box labeled "Value of 'X'" where users are expected to enter their calculated value.

### Explanation:
To solve for "X", follow these steps:

1. **Write the expression for the equilibrium constant \( K \) for the reaction:**
\[ K = \frac{[ \text{SO}_2 ][ \text{Cl}_2 ]}{[ \text{SO}_2\text{Cl}_2 ]} \]

2. **Set up an ICE (Initial, Change, Equilibrium) table to express the concentrations in terms of "X":**

|        | \(\text{SO}_2\text{Cl}_2 \) (g) | \(\text{SO}_2 \) (g) | \(\text{Cl}_2 \) (g) |
|--------|------------------------------|-------------------|-------------------|
| Initial | 1.50 M                         | 0.200 M           | 0.200 M           |
| Change  | -X                             | +X                | +X                |
| Equilibrium | 1.50 - X                     | 0.200 + X         | 0.200 + X         |

3. **Substitute the equilibrium concentrations into the \( K \) expression:**

### Reaction System and Reaction Quotient Calculation

#### Given Reaction:
\[ \text{SO}_2 \text{Cl}_2 (g) \rightleftharpoons \text{SO}_2 (g) + \text{O}_2 (g) \]

#### Equilibrium Constant:
\[ K = 0.520 \quad \text{at} \quad 400\, \text{K} \]

#### Initial Concentrations:
- \(\left[ \text{SO}_2 \text{Cl}_2 \right] = 1.50 \, \text{M} \)
- \(\left[ \text{SO}_2 \right] = 0.200 \, \text{M} \)
- \(\left[ \text{Cl}_2 \right] = 0.200 \, \text{M} \)

#### Calculation:
Calculate the reaction quotient, \( Q \), using the initial concentrations.

\[ Q = \frac{\left[ \text{SO}_2 \right] \left[ \text{Cl}_2 \right]}{\left[ \text{SO}_2 \text{Cl}_2 \right]} \]

\[ Q = \left[ ? \right] \times 10^{[ ? ]} \]

#### Input Fields:
- **Coefficient (green):** This field is for entering the coefficient in front of the \(10\).
- **Exponent (yellow):** This field is for entering the exponent.

After entering the values, click "Enter" to submit and check the calculated reaction quotient, \( Q \).

#### Graphs/Diagrams Explanation:
There are no graphs or diagrams in this image. The main visual elements are the chemical equation, the numerical values for the equilibrium constant and initial concentrations, and input fields for the reaction quotient calculation.

This setup is commonly used in educational platforms to help students practice calculating reaction quotients from initial concentrations, which helps in understanding chemical equilibrium concepts.
