Units for Rate Constants

Postby Daniel Dobrin 2F » Sun Mar 19, 2017 1:39 am

Hey everyone,

I had a quick question. What are the units for the rate constant k for 0, 1st, and 2nd order reactions? I know each one is different, but I can't remember what they are.

Thank you and good luck tomorrow!!!

Assuming time is in seconds:
Zero order: k has units M/s
First order: k has units s^-1
Second order: k has units M^-1 s^-1
