Describe with specific examples, 3 different methods of determining the rate Constant of a reaction.​

There is actually one method depending of the order of the reaction.

We will work with the reaction aA —> bB

We’ll start with the order 0:
rate=k[A]^0[B]^0=k=(1/a)(d[A]/dt)

d[A]=kadt

You integrate.

[A](t)-[A](0)=kat

Then you can access to k.

You do the same for an order 1 and 2 reaction.
The difference will be that you will have k[A]=(1/a)(d[A]/dt) and
k[A]^2=(1/a)(d[A]/dt)


You can also work with the Arrhenius law, it can be another method actually:
K(T)=Aexp((-Ea)/RT)

I hope I helped you :)
