First Order Equation

Postby Eunice Lee 1A » Sun Mar 17, 2019 8:33 am

How is ln[R]=-kt+ln[R]0 useful? What does it tell us?

This is the integrated rate law for a first order reaction. The integrated rate laws tell you how much concentration of something you have left after some time has passed.

this equation is the integrated rate law for first order reactions and to add to what the previous post said, you are able to graph this as just a downward straight line, because of the -k (slope) and the y intercept, ln [A]0

We can also use this equation to solve for initial concentrations or rate constant if needed.
