# Setting up a Reaction Table: Kinetics and Equilibrium

## Reaction Scenario

Suppose a 500. mL flask is filled with 0.10 mol of SO₂ and 1.1 mol of SO₃. This reaction becomes possible:

\[ 2\text{SO}_3(g) \rightleftharpoons 2\text{SO}_2(g) + \text{O}_2(g) \]

## Objective

Complete the table below, so that it lists:
- The initial molarity of each compound
- The change in molarity of each compound due to the reaction
- The equilibrium molarity of each compound after the reaction has come to equilibrium

Use \( x \) to stand for the unknown change in the molarity of \(\text{O}_2\). You can leave out the \( M \) symbol for molarity.

### Reaction Table

|              | SO₂ | SO₃ | O₂  |
|--------------|-----|-----|-----|
| **Initial**  |     |     |     |
| **Change**   |     |     |  x  |
| **Equilibrium** |     |     |     |

[Explanation] [Check]

## Instructions

- Fill in the initial concentrations based on the moles given and calculate the changes using the stoichiometry of the reaction.
- Determine the equilibrium concentrations using the initial and change values.

This activity will help you understand how to apply the concepts of chemical equilibrium and stoichiometry in reaction tables.

Expert Solution
Step 1

Given moles of SO = 0.10 mol 

Gicen moles of SO3 = 1.1 mol 

Initial moles of oxygen = 0 

We are given reaction at equilibrium and we have to complete ICE table
