FINAL - SECTION 5 Flashcards
1
Q
Reaction rate
A
Represented as [ ]/T and measures how fast concentration is (concentration and time)
2
Q
+ sign
A
Product
3
Q
- sign
A
Reactant
4
Q
What do you do with the mole quantity
A
Put it at the bottom of fraction in equation
5
Q
Unit of reaction rate
A
M/S
6
Q
Differential rate law
A
Measures rate and concentration
7
Q
Rate law
A
k[A]^n
8
Q
Zero order
A
Rate is constant and independant on concentration (k[A]^0)
9
Q
First order
A
Rate is dependant on concentration ( k[A]^1) and 2x
10
Q
Second order
A
Rate is dependant on concentration (k[A]^2) and 4x
11
Q
Units of k
A
- Zero order: M L s-1
- First order: s-1
- Second order: L M-1 s-1
12
Q
Multiple rate reaction
A
Overall order becomes the sum of reactant exponents ( rate = k[A]^m[A]^n, overall order is m+n)
13
Q
Integrated rate law
A
Concentration and time
14
Q
What do we do with minutes in integrated rate law
A
Convert to seconds
15
Q
“Plot of inverse”
A
Second order
