Question
Using the graphic below as a reference, describe what happens to a reversible reaction as it attains equilibrium.
#### Graph 2: Equilibrium with Equal Concentrations
- **Description**: Similar to the first graph, the concentrations of reactants (C_A and C_B) begin high and decrease over time, while the products (C_C and C_D) start low and increase. However, in this graph, the lines converge at the same concentration level.
- **Equilibrium Point**: Equilibrium is reached when the concentrations of reactants and products become equal.
#### Graph 3: Equilibrium on the Product Side
- **Description**: In this scenario, the reactants’ concentrations (C_A and C_B) decrease significantly, and the products’ concentrations (C_C and C_D) increase prominently. The final equilibrium point shows much higher concentrations of products than reactants.
- **Equilibrium Point**: The equilibrium lies on the product side, indicating a greater yield of products at equilibrium.
Understanding these different equilibrium scenarios is crucial in chemical kinetics and thermodynamics. They illustrate how altering conditions can shift the equilibrium position, affecting reactant and product concentrations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F81d865ca-ed2c-4f6d-a4cc-7f843242dec1%2Fb74707bd-e3c5-4ee7-a78a-d07253b5e9c8%2Fhitgyx_processed.jpeg&w=3840&q=75)
Transcribed Image Text:### Understanding Equilibrium Shifts in Chemical Reactions
The three graphs presented below illustrate how the concentrations of reactants and products change over time in chemical reactions reaching different equilibrium states. Each graph contains two curves representing concentrations of reactants (C_A and C_B) and two for products (C_C and C_D) as time progresses.
#### Graph 1: Equilibrium in the Middle
- **Description**: In this scenario, the reactants' concentrations (C_A and C_B) decrease over time while the products' concentrations (C_C and C_D) increase. Eventually, both reach a point where they level off and stay constant.
- **Equilibrium Point**: The equilibrium is established at a midpoint, where the concentrations of reactants and products level off, indicating the rate of the forward reaction equals the rate of the reverse reaction.
#### Graph 2: Equilibrium with Equal Concentrations
- **Description**: Similar to the first graph, the concentrations of reactants (C_A and C_B) begin high and decrease over time, while the products (C_C and C_D) start low and increase. However, in this graph, the lines converge at the same concentration level.
- **Equilibrium Point**: Equilibrium is reached when the concentrations of reactants and products become equal.
#### Graph 3: Equilibrium on the Product Side
- **Description**: In this scenario, the reactants’ concentrations (C_A and C_B) decrease significantly, and the products’ concentrations (C_C and C_D) increase prominently. The final equilibrium point shows much higher concentrations of products than reactants.
- **Equilibrium Point**: The equilibrium lies on the product side, indicating a greater yield of products at equilibrium.
Understanding these different equilibrium scenarios is crucial in chemical kinetics and thermodynamics. They illustrate how altering conditions can shift the equilibrium position, affecting reactant and product concentrations.
