Tuesday, 2-11 “Rate of Reaction” demos and notes Materials: Notebook and writing utensil. Nothing else should be out on the desk. If you’ve missed any of these notes you need to either get them from someone else in the class or come in before or after school to get help. Wednesday: Equilibrium notes and demo Thursday: Quiz, and Equilibrium Video`

Concentration If you have more reactants, you have more chances for collisions. Sorry… this one’s kind of boring and obvious…

Surface Area Generally Only Applies to Solids

Volume Really only applicable with gasses. You’re actually increasing the amount of energy (heat) in the system!

Catalysts/Inhibitors A catalyst provides an alternative route for the reaction with a lower activation energy.

Catalysts/Inhibitors Less Energy More Energy Normal Activation Energy Activation Energy with catalyst

Catalysts/Inhibitors Catalysts are NOT used up during a reaction. They do not experience any net change during a reaction. Concentration of catalyst in the reaction is a factor.
