Rate law for zero order reaction
Rate = K
Rate law for first order reaction
Rate = K[A]
Rate law for second order reaction
Rate = K[A]^2
Integrated rate law for zero order reaction
[A]=-kt+[A]o
Integrated rate for first order reaction
ln[A]=-kt+ln[A]o
Integrated rate for second order reaction
1 = kt + 1
