1
Q
differential rate law
A
rate=k[A]ⁿ
2
Q
zero order integrated
A
[A]=-kt+[A]₀
3
Q
first order integrated
A
ln[A]=-kt+ln[A]₀
4
Q
second order integrated
A
1/[A]=kt+(1/[A]₀)
5
Q
zero order half life
A
t1/2=[A]₀/2k
6
Q
first order half life
A
t1/2=.693/k
7
Q
second order half life
A
t1/2= 1/[A]₀k
8
Q
three collision theory ideas
A
1) reactant molecules must collide
2) reactant molecules must collide with the correct orientation
3) reactant molecules have to collide with enough energy to overcome the Eₐ barrier
9
Q
three ways to increase rate of reaction
A
1) increase reaction concentration (does not affect K or Eₐ)
2) Increase temp (increases k, does not affect Eₐ)
3) add a catalyst (lowers Eₐ and increases K)
