Chem 13

the study of rates of reactions (there speeds) and the pathway taken during the reaction (the mechanism of the reaction)

the greater the frequency and the greater the energy of collision between reactant particles, the greater the rate of reaction

a minimum energy that a molecule must possess if it is to react and do molecular "damage."

molecules thought to form a short-lived, high-energy, unstable arrangement of atoms, in which bonds are in the process of breaking and reforming

a substance that increases the rate of a chemical reaction without being consumed in the reaction

what group of proteins serve as biological catalysts

slows the rate of a chemical reaction by bonding to ("tying up") a catalyst

catalysts that exist in the same phase as the reactants

catalyst that is not in the same phase as the reactants

in order to explain the observed rate of a given reaction, chemists propose (theorize) a series of steps that describes the way in which a reaction proceeds

rate of a chemical reaction can often be described by

and equation that relates the reaction rate to the concentration of the reactants

what is k in the rate law
