rushwr · Answer

As to what I know 
The amount of products obtained during a constant time
The amount of reactants used up during a constant time
Time taken to obtain a constant amount of products.

Ok, that makes sense. Thank you!

no no wait. Let's go with tata's opinion !

Ok

taramgrant0543664 · Answer

rate=k[A]^2 for a second order reaction n=2
rate=k[A]^n[B]^m  so you would need to find exponents n and m
To find n and m you would need the products obtained and the reactants used and the rate at which they happen at there's normally a table and you figure out the exponents when one is constant and the others change
Using concentrations after you find the exponents you can get the rate constant k
I don't know if that makes sense, I'm not very good at explaining these questions!
