differential rate law
rate=k[A]ⁿ
zero order integrated
[A]=-kt+[A]₀
first order integrated
ln[A]=-kt+ln[A]₀
second order integrated
1/[A]=kt+(1/[A]₀)
zero order half life
t1/2=[A]₀/2k
first order half life
t1/2=.693/k
second order half life
t1/2= 1/[A]₀k
three collision theory ideas
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
three ways to increase rate of reaction
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)
