Rate of Reaction
Rate and extent of reaction
| Term | Definition |
|---|---|
| Particle size | the smaller the particle the faster the chemical reaction |
| Surface area | the amount of exposed surface of a substance |
| Catalyst | a substance that initiates or accelerates a chemical reaction without itself being affected |
| Enzyme | any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions |
| Temperature | the degree of hotness or coldness of a chemical (corresponding to its molecular activity and thus energy) |
| Activation Energy | the energy that an atomic system must acquire before a process (such as a reaction) can occur |
| Chemical Concentration | The amount of particles in the solution |
| Collision Theory | atoms, ions, and molecules can react to form products when they collide, provided that the particles have enough kinetic energy |
| Dependent variable | the variable that is measured in an experiment |
| Independent variable | the experimental factor that is manipulated; the variable whose effect is being studied |
| Rate of Reaction | measure of how fast a chemical reaction occurs, the speed at which reactants are consumed and products are produced in a given reaction |
| stirring | moves reacted particles out of way and makes new particles dissolve |
| Catalyst addition | increased rate of reaction, reducing activation energy need for the reaction to initiate |
| chemical reaction | a process in which one or more substances are changed into others |
