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
