3.5 Kinetics Flashcards
What is the rate equation general?
K[A]1[B]2[C]0
What is the definition of activation energy?
Minimum energy required for successful collisions
What are the conditions for successful collisions?
Sufficient energy
correct orientation
What does the Maxwell-bowman graph depict?
Concentration of particles against energy
How does a higher temperature impact a Maxwell bowman graph?
lower conc of particles `
What is the definition of rate?
The change in concentration of a reactant or product in a given time
How does the rate of reaction increase?
faster particles means more collisons
How does a 0 order reactant impact rate?
Has no impact
How does a 1st order reactant impact rate?
mirrored in rate
double [A] doubles rate ect
How does a 2nd order reactant impact rate?
Squares it
Double [A] quadruple rate
What is the definition of half life?
Time taken for the concentration of 1 reactant to half
How do you deuce first order from a graph of concentration and time?
the half life will remain constant
t=1 to t=1/2 to t=1/4 to t=1/8
How do higher temperatures impact K?
Make it larger
rate increases as temperature increases
What is the rate determining step?
the slowest step in a reaction that must occur first to allow the rest of the reaction to occur
How do you find the rate determining reactant?
If its in the rate equation
What does the order of the reactant tell you about the RDS?
How many particles of it are involved
What is the Arrhenius equation?
K=Ae^-Ea/RT
