![### Numerical Equilibrium Problem for Educational Use
**Subject:** Chemical Equilibrium
---
#### Problem Statement:
Consider the following fictional reaction:
\[ 2AB(\text{aq}) \rightleftharpoons 2A(\text{aq}) + B_2(\text{aq}) \]
The equilibrium constant for this reaction, \( K \), is given as:
\[ K = 9.8 \times 10^1 \]
#### Initial Conditions:
- You start out with a 5.0 M solution of \( AB \), \( A \), and \( B_2 \).
#### Objective:
Determine the concentration of each species (\( AB \), \( A \), and \( B_2 \)) when the reaction reaches equilibrium.
*Note: When solving this problem, you are not allowed to put the algebra equation in your calculator to solve for \( x \).*
---
### Key Concepts:
1. **Equilibrium Constant (K):**
The equilibrium constant \( K \) for the reaction is a measure of the ratio of the concentrations of the products to the reactants at equilibrium, each raised to the power of their stoichiometric coefficients.
2. **ICE Table:**
An ICE (Initial, Change, Equilibrium) table is typically used to organize the initial concentrations, the changes in concentrations, and the equilibrium concentrations for reactions.
3. **Algebraic Manipulation:**
To find the equilibrium concentrations, set up the equilibrium expression using the initial concentrations and the changes that occur as the reaction proceeds to equilibrium. Solve the resulting algebraic equation without the use of a calculator.
---
### Steps to Solve:
1. Write the expression for the equilibrium constant \( K \):
\[ K = \frac{[A]^2 [B_2]}{[AB]^2} \]
2. Set up an ICE table based on the initial concentrations and the changes that occur as the reaction reaches equilibrium.
3. Substitute the equilibrium concentrations into the equilibrium expression and solve for the unknowns.
By following these steps, you can systematically determine the equilibrium concentrations for the given chemical reaction. For an accurate and detailed solution, write out the full ICE table and algebraic manipulations on paper.
---
**Additional Exercises:**
- Practice setting up and solving similar equilibrium problems.
- Learn to balance chemical equations and understand the significance of stoichiometric coefficients.
- Explore the concept of reaction quotient and how it relates to the equilibrium](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd840dc46-e3d2-47d1-9b6d-e93b2d8faa77%2F1b53f683-c616-4483-812c-d61c2e7dcd7b%2F5jrsmp.jpeg&w=3840&q=75)
