Writing rate laws
When a reactant is first order is it necessary/proper to write the exponent of 1 in its rate law? For 0 order reactions, should the reactant be included in the rate law at all?

Re: Writing rate laws
When the reactant is first order, you do not need to include the exponent, when the reactant is 0 order, you do not need to write the reactant at all.

Also, when you have a zero order reaction, the rate is equal to the equilibrium constant k, so you don't need to include the reactant.

Re: Writing rate laws
If a reaction is zero order it should not be included in the rate law. If it was there, it would falsely report that concentration of the reactant influences the rate of reaction. It does not, so it should not be included.

Re: Writing rate laws
It's not necessary to write the 1 in first order reactions, the one is just implied if you write out the reactant with no exponent
