Calculations:

Calculate the ratio of products to reactants for each part of the lab. Show the set up as well as the simplified ratio. (2 points for each calculation, or 6 points total)

1: 1.07
2.1.05
3.1.07 ratio = P/R

Conclusion:

Answer the following questions in complete sentences, giving detailed explanations and support for each of your answers.

1. Explain in your own words what it means for a chemical system to be in the state of dynamic equilibrium. (4 points)

Dynamic equilibriumis a state of balance where the forward and the reverse reactions occur at the same time and the rates are the same. The reverse reaction and forward reaction are kept constant with time. Only closed systems have equilibriums.

2. Describe what you observed in each part of this lab. Do you think that each part of this activity helped to illustrate the concepts of equilibrium? Explain your answer completely in paragraph form. (4 points)

The reaction was a two-way reaction and it did help illustrate equilibrium because as the reactants began to decrease, the products began to increase.

3. How did the calculated ratios of product to reactant compare in the three parts of this activity. Explain, in paragraph form, if these ratios illustrate the concept of the law of mass action and the equilibrium constant of a system. (4 points)

The ratios in all 3 parts were very similar in the way the decreasing and increasing happened at the same time and I could SEE the equilibrium in effect.

4. What determines when a system reaches equilibrium? What observations can be made about a system once equilibrium has been established? (3 points)

The equilibrium was in effect when the numbers started to repeat. I could visually see, participate and understand the equilibrium as it occured.

5. What does the value, or magnitude, of the equilibrium constant (K) tell you about an equilibrium system? Be specific with your answer. (4 points)

At a given temperature a reaction will have a temp of k the equilibrium will be constant. Along with the magnitude and value.

6. In real life, a given system can approach equilibrium from different starting points but will still have the same equilibrium constant. How is this possible? Explain your answer in complete sentences. (4 points)

This is possible through the two-way reaction as the points can change seperately.
