Chapter 12.1 and 12.4 of A Natural Approach to Chemistry Reaction Rates
Rates of Reactions How fast does a reaction occur?
Why Do We Care? Sometimes we need reactions to happen quickly. Sometimes we need to slow reactions down.
Why Do We Care? How do we know if a reaction is going to occur quickly or slowly? Better yet, how can we control the rate of a reaction?
Rate of Reaction Rate of Reaction - how fast a reaction occurs -how quickly the amount of reactants __________ -how quickly the amount of products __________ decrease increase
Collision Theory Collision Theory – In order to react, reactant molecules must collide with each other How does this relate to reaction rates? In order to increase reaction rate, we must increase the number of collisions.
