Chemical Kinetics Flashcards
The slowest step is the
Rate determining step
The reaction order is the
Sum of exponents
For 0 order, what is the rate?
rate = K
What are the units for 0 order?
Ms-1
For 1st order, what is the rate?
rate = K[A]
What are the units for 1st order?
s-1
For 2nd order, what is the rate?
rate = [A][B]
What are the units for 2nd order?
m-1s-1
What is the equation for half lives of 0 order?
[A0]/2k
What is the equation for half lives of 1st order?
ln(2)/k
What is the equation for half lives of 2nd order?
1/2 k[A0]
What does the Collision Theory of Chemical Kinetics state?
The rate of a reaction is proportional to the number of collisions per second between reacting molecules
An effective collision is one that leads to the formation of
Products
An effective collision only occurs if molecules
Collide in the correct orientation and sufficient force
