Rate Law and Order of Reaction Flashcards
1
Q
What does the reaction rate depend on?
A
The concentration of the reactants
2
Q
Rate Law Equation
A
An expression that shows how the rate depends on the concentration of the reactants
3
Q
Rate Constant
A
- “K”
- Determined experimentally
4
Q
Order of Reaction
A
- The exponent
- Describes relationship between the initial concentration of a particular reactant and the rate of reaction
5
Q
First note about rate law
A
The concentrations of products do not appear in the rate law
6
Q
Why are the concentrations of products not present in the rate law
A
Because reaction rate is being studied under conditions where the reverse reaction does not contribute to the rate
7
Q
Second note about rate law
A
- The value of the exponent must be determined by experiment
- It can not be written from the balanced equation
8
Q
Differential Rate Law
A
Expresses how the rate depends on concentration
9
Q
Integrated Rate Law
A
Expresses how the concentration depends on time
