zero order in rate laws

Postby Gabriela Carrillo 1B » Sun Mar 04, 2018 11:15 pm

If a reactant is zero order do we include it in the rate law or write it without it? For example: rate=k[A][B]^2[C]^0 or rate=k[A][B]^2?

If a reactant is zero order, you do not include it in the rate law because it won't affect the rate of the reaction.

Unless the problem wants you to write it out specifically, probably not

You write it without it since it has no affect

No, the zero order reaction has no effect on the rate law so normally its not included.

If it is zero order the rate law is not dependent on the concentration of that reactant so it technically doesn't need to be included.

We can include them but its . not needed.

Since it ends up being 1, I wouldn't include it. It makes the equation look cluttered

You can leave it out because it has no effect on the rate.
