3rd order

Postby andrea guzman 1F » Sun Mar 17, 2024 9:37 pm

Hi how would we derive the third order integrated rate law and half-life?

We would derive the third-order integrated rate law by using the equation [A] t = -kt + [A] naught. We would use the equation [A] naught/2k in order to solve for the half-life. You can use what is given to you in the equation to plug into these equations in order to solve for your desired value.

Hi,
since they all build off each other, I would assume

rate=k[a]^3. hence third order
for the units it would be M^2
I am not sure there if there is an integrated rate law. I hope this helps!
