### Question 15.85

The following rate laws were each derived from an elementary reaction. IN each case, write the chemical equation for the reaction, determine its molecularity, and draw a proposed structure for the activated complex:
(A) Rate = k[CH3CHO](Products are CH3 and CHO)
(B) Rate = k[I]^2[Ar](Products are I2 and Ar)
Rate = k[O2][NO](Products are NO2 and O)

### Re: Question 15.85

How do we determine the molecularity given the rate laws?

Can someone please explain how we draw the activated complex?

You can look at the number of reactants in the chemical equation to determine the molecularity of the rate laws.
If there is only one reactant=unimolecular
two reactants=bimolecular
three reactants=termolecular (highly unlikely in real life tho...)
