14a Flashcards
the study of the rates of reactions and the steps by which they occur
kinetics
kinetics seeks to determine what happens ___ the start and the endpoint of a reaction
between
the collision theory says what 3 conditions must be met for any reaction to occur?
1- particles must collide before they can react
2- the collision must be properly oriented for the necessary rearrangement of atoms and electrons
3- be forceful enough (possessing enough energy to form products)
explains why reactions occur at faster or slower rates, depending on reaction conditions
the collision theory
as a rule, the ___ the activation energy is, the faster the reaction will occur
lower
breaking bonds in molecules always requires
energy
what can be thought of as the minimum amount of energy needed to convert the reactants into the activated complex?
activation energy
in the same phase as the reactants or in solution with a reactant
homogeneous catalyst
a substance used to reduce a catalyst’s undesirable effects
inhibitor
A theoretical, unstable, energetic group of reactants that forms as a transitional structure during a chemical reaction.
activated complex
The speed at which reactants disappear or products appear in a chemical reaction.
reaction rate
A naturally occurring protein molecule that acts as a catalyst
enzyme
