1 Static & Dynamic Equilibrium
BY: Tekanenhorens Brass, Harjas Mann, Zachary Posman

2 Whaaaaaaaaattt? Static equilibrium exists when a system remains at a given point or is kept immobile without active dynamic processes being involved. Dynamic equilibrium is the result of two opposing processes occurring at the same rate so that no visible change takes place in a reaction system. There are three types of dynamic equilibrium: Phase or physical equilibrium Solubility equilibrium Chemical equilibrium

3 Static Equilibrium Immobile No movement what so ever Staying still
Like its not f*cking moving at all That’s basically static equilibrium That’s it

4 Are these rocks moving?

5 Are these rocks moving? NO!

6 Dynamic Equilibrium On the contrary, in chemistry, when a system is in a state of equilibrium, the particles in the system are constantly moving and change even though there is no visible change. The rate of the reactants and the rate of products are equal. This is why in a dynamic equilibrium system there is no change that takes place in the reaction system.

7 Phase or ‘Physical’ Equilibrium
When a single substance is found in several phases within a system as a result of a physical change, this phenomenon is known as phase or physical equilibrium For example, in a water bottle, molecules are constantly moving from the liquid phase to gas phase but this occurrence cannot be seen.

8 This is a water bottle

9 Solubility Equilibrium
Solubility equilibrium is a state in which a solute is dissolved in a solvent or a solution, and an excess of the solute is in contact with the saturated solution. For example, tea is a solution where the solvent is water and the solute is sugar. When excess sugar is poured, it cannot dissolve anymore and it sinks to the bottom. It seems as though nothing is occurring but in reality, the sugar on the bottom is constantly dissolving at the same rate as dissolved sugar is is returning to a solid.

11 Chemical Equilibrium Chemical equilibrium is dynamic equilibrium that results from two opposing chemical reactions that occur at the same rate, leaving the composition of the reaction system unchanged. It has to be a chemical change between a reaction and a product. For example, the conversion of nitrogen tetroxide (N2O4) into nitrogen dioxide (NO2). In this reaction, the reactants changes into products and the product changes into reactants simultaneously at the same rate.

12 N2O4  2 NO2
