Equilibrium and Concentration: Equilibrium And Concentration Gizmo Answers
Chemical equilibrium is a state in which the concentrations of the reactants and products of a chemical reaction do not change over time. This occurs when the forward and reverse reactions are occurring at the same rate.
The factors that affect equilibrium concentrations include temperature, pressure, and the concentration of the reactants and products. Temperature affects the equilibrium constant, which is a measure of the extent to which a reaction proceeds. Pressure affects the equilibrium concentrations of gases.
The concentration of the reactants and products affects the rate of the forward and reverse reactions.
Examples of Chemical Reactions that Reach Equilibrium
- The Haber process, which is used to produce ammonia
- The water-gas shift reaction, which is used to produce hydrogen
- The dissociation of hydrogen iodide

Describe the Equilibrium and Concentration Gizmo, Equilibrium and concentration gizmo answers
The Equilibrium and Concentration Gizmo is a virtual laboratory that allows students to investigate the factors that affect equilibrium concentrations. The Gizmo includes a reaction chamber, a thermometer, a pressure gauge, and a data table.
Explain how the Gizmo can be used to investigate equilibrium
The Gizmo can be used to investigate the factors that affect equilibrium concentrations by changing the temperature, pressure, or concentration of the reactants and products. The Gizmo then measures the changes in the concentrations of the reactants and products over time.

Identify the equilibrium concentrations of the reactants and products
The equilibrium concentrations of the reactants and products are the concentrations at which the forward and reverse reactions are occurring at the same rate. In the example above, the equilibrium concentrations are:
- [A] = 0.50 M
- [B] = 0.50 M
- [C] = 0.00 M
Discussion
Discuss the implications of the data collected from the Gizmo
The data collected from the Gizmo shows that the equilibrium concentrations of the reactants and products are affected by the temperature, pressure, and concentration of the reactants and products. This data supports the principles of chemical equilibrium, which state that the equilibrium concentrations of the reactants and products are constant at a given temperature and pressure.
Explain how the results support the principles of chemical equilibrium
The results of the Gizmo experiment support the principles of chemical equilibrium by showing that the equilibrium concentrations of the reactants and products are constant at a given temperature and pressure. This is because the forward and reverse reactions are occurring at the same rate at equilibrium, so the concentrations of the reactants and products do not change over time.
Compare the results obtained from the Gizmo to those predicted by theory
The results obtained from the Gizmo are consistent with those predicted by theory. The equilibrium concentrations of the reactants and products are constant at a given temperature and pressure, and the equilibrium constant is a measure of the extent to which a reaction proceeds.
