Kinetics Flashcards
1
Q
factors that influence reaction rate
A
- concentration
- physical state
- temperature
2
Q
reaction rate:
concentration (2)
A
- molecules must collide to react
- Increase # molecules, increase # of collisions
3
Q
reaction rate:
physical State
A
- molecules must mix to collide
- increased Surface Area, faster reaction
4
Q
reaction rate:
temperature
A
- molecules must collide with enough energy to react
- Increase temp, increase reaction rate due to ^ in energy
5
Q
___ [reactants], [products] ____
A
decrease, increase
6
Q
Rate equation
A
rate = k x [A]m x [B]n
7
Q
m=1
A
if the rate doubles when [A] doubles
8
Q
m=2
A
if the rate quadruples when [A] doubles
9
Q
m=0
A
if the [A] doubles but no change in the rate
10
Q
1st order rate =?
A
k[A]
11
Q
2nd order rate=?
A
k[A]2
12
Q
zero order rate=?
A
k
13
Q
1st order rxn? (2)
A
ln[A]f-ln[A]i=-kt
ln[A]f=-kt+ln[A]i
14
Q
2nd order rxn?
A
1/[A]f=kt+1/[A]i
15
Q
zero order rxn?
A
[A]f=-kt+[A]i
