Rate constant = k

[Jessica Yang 1J]

I was wondering when we were calculating k, would we calculate k based on the initial concentrations and reaction rates because I remember taking notes about the importance of initial reaction rates?

There are multiple ways of calculating k. If we have the initial concentrations and rates, we can use the differential rate law, rate = k [A]^n to calculate k, in which n is the order of the reaction, and [A] is the initial concentration of the reactants.
