  1. By: Aaron Mikel and Esai Garcia Equilibrium

  2. Definition of equilibrium • Equilibrium is defined as; A state in which the forward and reverse paths of a change take place at the same rate • In simpler terms, equilibrium is when all parts of something being equal or the same

  3. Types of equilibrium • A physical equilibrium is defined as: a physical change that does not go to completion, a physical equilibrium is established between the forward and reverse changes. • When all physical elements of something are equal or the same. A chemical equilibrium is defined as: When a chemical reaction does not go to completion, a chemical equilibrium is established between the forward and reverse reactions. When all chemical elements of something are the same or equal. Physical Chemical

  4. Factors affecting chemical equilibrium • When a change is introduced to a system of equilibrium, the equilibrium shifts in the direction that relieves the change and cancels it out to again restore equality. • The three main factors affecting equilibrium are Temperature, Pressure and Concentration.

  5. Temperature can greatly affect chemical equilibrium

  6. How Temperature affects chemical equilibrium • The principle that was founded by Le Chatelier states that; adding heat to a system of equilibrium would move the equilibrium to favor the reverse reaction. If you add more temperature and heat something, there is going to be less of it to deal with. If you boil water, after awhile, there will be less water to deal with.

  7. Pressure can greatly affect equilibrium

  8. How Pressure affects Chemical equilibrium • Using the same principle of heat affecting a chemical equilibrium, if you add more pressure to something, the more you will have to deal with. The reason why this is true is because the more pressure there is, the less gas molecules are needed to keep that same pressure, this allows more of something to be produced.

  9. Concentration can greatly affect equilibrium

  10. How concentrations affect chemical equilibrium • If you take the reactants of something out, the chemical equilibrium of something would be forced to help create more of the reactant, if it did not do this, the substance wouldn’t have equilibrium and then it would become unstable.

  11. Equilibrium is simply put, a state of perfect balance.

  12. But if things don’t get to equilibrium…

  13. We hope you enjoyed our featured presentation Thank you for watching

  14. By: Aaron Mikel and Esai Garcia This has been “equilibrium”

  15. And now for our quiz…

  16. Q.1 What are two things that equilibrium are used for? Q.2 What are the two different kinds of equilibrium? Q.3 What can temperature do to equilibrium? Q.4 What can pressure do to equilibrium? Q.5 What can concentration do to equilibrium?

  17. Halfway done…

  18. Q.6 Define chemical equilibrium • Q.7 How is chemical equilibrium different than physical equilibrium? • Q.7 Give an example of physical equilibrium • Q.8 What happens in chemical equilibrium? • Q.9 Once equilibrium is reached, how does it react to change?

  19. Final question!!!

  20. What would you rate our presentation? • 1- very bad, needed a lot of work • 2-bad, needed work • 3-ok, average but still not very good • 4-good, clear and understandable • 5-great, met all requirements and was good all around. • Please be honest :D

  21. Answer Key Q.1 They are pressure, temperature or concentration. Q.2 Physical and Chemical Equilibrium Q.3 It would shift the equilibrium in the direction the heat removes to the system. Q.4 It would shift the equilibrium where pressure is decreasing. Q.5 It would shift in the direction that produces ammonia.

  22. Second Half of Answer Key Q.6 Is established between the forward and reverse reactions. Q.7 Physical equilibrium is changes and chemical is reactions. Q.8 A chemical reaction does not go to completion and is established between the forward and reverse reactions. Q.9 The equilibrium shifts in the direction that relieves the changes.

  23. Last question to the Answer Key Q.10 The answer is your number that u have gave us for are presentation. Hope you liked our slide show on Equilibrium (:
