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

Types of equilibrium

Physical Chemical

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.

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.

Temperature can greatly affect chemical equilibrium

Page 6: By: Aaron Mikel and Esai Garcia. Definition of equilibrium  Equilibrium is defined as; A state in which the forward and reverse paths of a change take.

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.

Pressure can greatly affect equilibrium

Page 8: By: Aaron Mikel and Esai Garcia. Definition of equilibrium  Equilibrium is defined as; A state in which the forward and reverse paths of a change take.

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.

Concentration can greatly affect equilibrium

Page 10: By: Aaron Mikel and Esai Garcia. Definition of equilibrium  Equilibrium is defined as; A state in which the forward and reverse paths of a change take.

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.

Equilibrium is simply put, a state of perfect balance.

But if things don’t get to equilibrium…

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

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.

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.
