|
Chemical reaction |
A process that produces chemical change |
|
|
Reactant |
Substances that exist before the reaction begins |
|
|
Product |
Substances that form as a result of the reaction |
|
|
Chemical equation |
Tells chemists at a glance the reactants, products, physical state, and the proportions of each substance present. Kind of like shorthand ... Not writing everything out. |
|
|
Endothermic reaction |
chemical reaction in which heat energy is absorbed |
|
|
Exothemic reaction |
Chemical reaction in which heat energy is released |
|
|
Physical change |
Changes in physical property such as size, shape, stable of matter (solid, liquid, gas) |
|
|
Chemical change |
Produces new substances that have properties different from those of the original substance |
|
|
Activation energy |
Minimum amount of energy needed to start a chemical reaction |
|
|
Rate of reaction |
Measure of how fast a chemical reaction occurs |
|
|
Enzyme |
A type of protein that speeds the rate of chemical reaction in the body but is not used up or changed itself in anyway during the reaction. Catalysts that are large protein molecules that speed up or slow down reactions needed for your cells to work properly. |
|
|
Inhibitor |
Substance that slows down a chemical reaction, making the formation of a certain amount of product take longer |
|
|
Catalyst |
A substance that speeds up a chemical reaction |
|
|
Concentration |
The amount of substance present in a certain volume |
