Rate of Reaction

Rate and extent of reaction

TermDefinition
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
