

I can compare the entropy of solids, liquids and gases. (C2.2e)
I can draw and analyze a diagram to show the activation energy for an exothermic reaction that is very slow at
room temperature. (C2.3b)

I can predict how the rate of a chemical reaction will be influenced by changes in concentration, and
temperature, pressure. (C5.r1a)

I can explain how the rate of a reaction will depend on concentration, temperature, pressure, and nature of
reactant. (C5.r1b)
I can describe equilibrium shifts in a chemical system caused by changing conditions (Le Chatelier’s Principle).
(C5.3a)
I can predict shifts in a chemical system caused by changing conditions (Le Chatelier’s Principle). (C5.3b)
I can predict the extent reactants are converted to products using the value of the equilibrium constant. (C5.3c)
I can predict if a chemical reaction is spontaneous given enthalpy and entropy changes for the reaction using
Gibb’s Free Energy. (C3.4e)
I can explain why some endothermic reactions are spontaneous at room temperature. (C3.4f)
I can explain why gases are less sloluble in warm water than cold water. (C3.4g)

Enduring Understanding(s):



Changing conditions will cause shifts in the equilibrium of a chemical reaction.
In a closed system, many reactions reach equilibrium.
The concentration of a solution affects the reaction rate of chemical reactions.
Essential Questions(s):


How do changing conditions affect the equilibrium of a chemical system?
How does the concentration of a solution affect the rate of chemical reactions?
