Chemical Kinetics Flashcards
rate of reaction
chemical kinetics
what is the unit of rate
molar second
what consumes more energy
high speed reactions
calculations belonging to chemical equation
stoichometry
rate what over time
decreases
does the reaction ever reach completion?
no
measuring the change in the degree of rotation of plane-polarized light caused by one of the components over time
Polarimetry
measuring the amount of light of a particular wavelength absorbed by one component over time
Spectrophotometry
can measure the concentrations of various components in a mixture
Gas chromatography
why is rate law important?
so that we can control reactions
the time it takes for the original amount to reduce to 1/2
half life
can you make radio activr stuff decay faster?
no
does the half life for the first order depend on concentration?
no
what is activation energy
minimum amount of energy required for reaction to become product
in a graph where is activation energy found
reactant to the top of the hill
what is a chemical reaction
particles colliding with each other
what is a normal rate of collision
10 to the ninth power collisions per second
simple steps of reaction
mechanisms
what are the steps called
elementary steps
what is a intermediate compound
a compound available in the elementary steps and not in the reaction.
The number of reactant particles in an elementary step is called its
molecularity
are substances that affect the rate of a reaction without being consumed
catalysts
what is the rate determining step
the slowest reaction
where are catalyst usually seen first
reacants
