4.4 Rate Laws And Mechanisms Flashcards
1
Q
What are the rate laws?
A
Zero order reaction: K = [A]^0
First order reaction: K = [A]
Second order reaction: K = [A]^2
2
Q
How do you find what order your reaction is?
A
-You will be given data.
-Compare the first two trials (1 & 2) and find the order in respect to what is given. Compare the second two trials (2 & 3) and find the order in respect to what is given.
-Finish by writing out the rate law
(Rate = k [ ] [ ])

Q
Intermediate versus catalyst:
A
Intermediate: Something you don’t start with but will be used in the second reaction.
Catalyst: Is used to sped up the first reaction and is a product in the final reaction.
