Unit 12 Reaction Rates and Equilibrium
Rates
-
Measure the speed of any change that occurs within an interval of time
Collision Theory -
Atoms, ions, and molecules can react to form products when they collide
Activation energy -
the minimum amount of energy that particles must have to react .
activated complex -
arrangement of atoms at the peak of the activation energy barried
transition state -
"activated complex"
catalyst -
a substance that increases the rate of reaction without used up itself during the reaction
inhibitor -
substance that interferes with the action of a catalyst
reversible reactions -
the reactions occur simultaneously in both directions
chemical equilibrium -
state in which the forward and reverse reactions take place at the same rate
le chatelier's principle -
if a stress is applied to a system in a dynamic equilibrium, the system changes to relieve the stress
free energy -
extra energy available to do work
entropy -
the disorder of a system
law of disorder -
processes move in the direction of the maximum disorder or randomness
