This is the formula used to integrate the rate law for a first-order process
ln([A]t/[A]o)=-kt
[A]o=the initial concentration of A.
[A]t=the concentration of A at some time, t, during the course of the reaction.
You can manipulate the formula to create:
ln[A]t-ln[A]o=-kt
Here is the formula used to integrate the rate law for a process that is second-order:
1/[A]t-1/[A]o=kt
ln([A]t/[A]o)=-kt
[A]o=the initial concentration of A.
[A]t=the concentration of A at some time, t, during the course of the reaction.
You can manipulate the formula to create:
ln[A]t-ln[A]o=-kt
Here is the formula used to integrate the rate law for a process that is second-order:
1/[A]t-1/[A]o=kt
