Kinetics quest
| Term | Definition |
|---|---|
| What are Chemical Kinetics | the study of reaction rates and reaction pathways |
| Collision theory | - In order for a chemical reaction to occur the particles must collide effectively - The more effective the collisions, the faster the reaction rate |
| Effective collisions | A collision between particles that will lead to a chemical change |
| Sufficient energy | the amount of activition energy needed to break the bonds for reacting particles |
| Proper orientation | reacting particles must collide with the proper geometry so that the reacting particles can rearrange into the products |
| Elementary reactions | A chemical reaction which occurs by a single collision (usually two particles or fewer |
| Activated complex | A high energy temporary state formed when the reacting particles collide |
| Reaction mechanism | A series of sucessive steps by which an overall reaction occurs (usually contains temporary intermediates) |
| Temperature | The higher the temperature (kinetic energy) the faster the reaction because particles will collide more frequently and with greater force |
| Phase of matter | For a particular substance, the rate of reaction increases as the substance changes from a solid to a gas |
| Pressure | An increase in pressure will cause an increase in reaction rate for gaseous reactants only |
