Rate of zeroth order reaction
R = k
Rate of first order reaction
R = k [A]
Rate of second order reaction
R = k [A]^2
Integrated Rate Law of zeroth order reaction
[A] = [A0] - kt
Integrated Rate Law of first order reaction
[A] = [A0] * e^-kt
Integrated Rate Law of second order reaction
1/[A] = 1/[A0] + kt
Units of rate constant of zeroth order reaction
M/s
Units of rate constant of first order reaction
1/s
Units of rate constant of second order reaction
1/M*s
Trick for finding units of rate constant
M^1-n t^-1
