|
reaction kinetics
|
the study of the rate of chemical reaction and the pathways by which chemical reactions occur
|
|
|
reaction rate
|
measured as a change in concentration per time
|
|
|
rate law expression
|
a mathematical relationship between concentration of reactants and the reaction rate
|
|
|
overall reaction order
|
the sum of the reaction orders for all the reactants
|
|
|
half life
|
the time it takes for the concentration of a reaction to reach half of its initial value
|
|
|
activation energy
|
the minimum amount of energy needed for tyhe reaction to occur
|
|
|
reaction mechanism
|
the detailed step by step description of how a reaction is believed to occur at the molecular level
|
|
|
elementary step
|
one step in the mechanism
the elementary steps will sum to the overall reaction |
|
|
molecularity
|
the number of participating particles in an elementary step
|
|
|
rate determining step
|
the slowest step of all the elementary steps in the mechanism
|
|
|
reaction intermediate
|
a species that is foemed in one elementary step but is consumed in a subsequent step of the mechanism
|
|
|
catalyst
|
something that speed up the rate of the reaction but is not consumed in the reaction
|
