How can physical changes lead to dynamic equili
ium?
From the video- Give an example of how chemical equili
ium is used in our world
How can you predict the position of equili
ium for a chemical reaction?
What is the formula and variables of the equili
ium constant?
*The specific ______________________ position reached by a system depends on the initial concentration of each substance
What does the value of K tell us about the equili
ium position?
· If K is close to one?
· If K is greater than one?
· If K is less than one?
How can graphs represent the dynamic equili
ium of a chemical reaction?
Example of Rates of Reaction Graph:
the reaction has reached equilibirum when the rate of forward and reverse reactions is Equal/Constant (circle only one).
Example of concentration Graph:
the reaction has reached equilibirum when the concentration of reactants and Products is Equal/Constant (circle only one).
