equilibrium hem regents

• Collision Theory: What are the two components necessary for a collision to be "effective"?

• Reaction Rates: What are the five factors that can influence the rate of a reaction, and why?

• PE Diagrams: Know how to label the diagram before and after the addition of a catalyst, how to draw a curve for exothermic and for endothermic reactions, and how to determine missing values for a diagram when given others.

• Entropy: Be able to identify the five changes that result in an increase in entropy and explain why those changes increase entropy.

• Spontaneity & Gibbs Free Energy: Know how to calculate changes in free energy based on enthalpy and entropy values and be able to identify whether a reaction will be always spontaneous, never spontaneous, or spontaneous only at low/high temperatures based on its chemical equation.

• Dynamic equilibrium: What are the four conditions needed for dynamic equilibrium to occur?

• Le Chatelier's Principle: How will equilibrium shift and change the amount of reactant and product present in response to the following stresses: increasing/decreasing concentration? increasing/decreasing temperature? increasing/decreasing pressure?
