When to use rate equations

Postby Ryan Neis 2L » Mon Mar 05, 2018 11:26 pm

How can you determine whether or not you need to use a regular rate law equation versus an integrated rate law equation when given certain values?

Integrated rate laws are used when describing change in concentrations over time (finding [A]t when given [A]0 and k, for example), while regular rate laws are just used when you are given concentrations and a rate and need to calculate k.

Is or when is a time when you would need to use both?

I believe there will be cases when both will be needed to solve problems
The first step of a problem could ask for us to use regular rate laws and given concentrations and a rate and to calculate k.

This k would be used with integrated rate laws to find the change in concentrations over time.
