Reaction Rates
Rates of reaction
| Term | Definition |
|---|---|
| What does the collision theory say about the collisions? | Collisions must happen for reaction to occur |
| What does the collision theory say about the energy of the collisions? | Collisions must occur with enough force or energy. |
| What does the collision theory say about the orientation of particles? | The particles must be aligned correctly. |
| What does it mean to say there is a fast reaction rate? | There are a large number of collisions, so that a lot of product is being made. |
| What does it mean to say there is a slow reaction right? | There are only a few collisions occurring, so that only a small amount of product is made. |
| Define the term concentration. | concentration is the amount of material present. |
| How does a high concentration change the rate of reaction? | The reaction will go faster. |
| How will the low concentration change the rate of reaction? | The reaction will go slower. |
| How will the high temperature affect the rate of reaction? | High temperature means the particles have more energy so they will move faster, and there will be more collisions. The reaction will go faster. |
| How will a low temperature affect the rate of the reaction? | Low temperature means the particles will have less energy and they will move slower. So, there will be fewer collisions. The reaction will go slower. |
| What is surface area? | Surface area is the amount of particles on the outside. |
| How can surface area be increased? | The material can be cut into pieces or ground up. |
| How can service area be decreased? | The particles can be packed together. |
| If the surface area is increased, what will happen to the rate of reaction? | The reaction will go faster. |
| If the surface area is decreased, what will happen to the rate of the reaction? | The reaction will go slower. |
| What is the purpose of a catalyst? | A catalyst lowers the activation energy. |
| What happens to a catalyst during a reaction? | The catalyst is unchanged. |
| What is unique about an enzyme? | Enzymes are catalyst in living things. |
