Kinetics Flashcards
Define rate of reaction.
The change in concentration with a unit of time.
What is the rate constant?
The rate at the start of a reaction
What does the rate expression provide the information of?
The contribution of the species which do not affect the reaction rate.
What is the order of a reaction?
The power to which the concentration of that species is raised in the rate equation.
If the rate is not affected by the concentration of a species what is the order of the reaction?
0
If the rate is directly proportional to the concentration of the species what is the order of the reaction?
1st
if the rate is proportional to the square of the concentration of the species, what is the order of the reaction?
2nd
How can you calculate rate?
Rate = k [A] [B]
How do you find the units of the k?
Cancel out the units
How do you calculate k?
k = Rate / [A] [B]
What happens to K if the rate of the reaction increases?
Increases because the concentrations stay constant
