This sourceThe reaction or reaction step is an isomerization if there is only one product molecule, or a dissociation if there is more than one product molecule. In either case, the rate of the reaction or step is described by the first order rate law : \frac{d \left [ \ce A \right ]}{dt} = -k_r \left [ \ce A \right ] , where is the concentration of species A, is time, and is the reaction rate constant. As can be deduced from the rate law equation, the number of A molecules that decay is proportional to the number of A molecules available. An example of a unimolecular reaction, is the isomerization of cyclopropane to propene: center Unimolecular reactions can be explained by the Lindemann-Hinshelwood mechanism. == Bimolecular reactions == In a bimolecular reaction, two molecules collide and exchange energy, atoms or groups of atoms. This can be described by the equation A + B -> P which corresponds to the second order rate law: \frac {d[\ce A]}{dt} = -k_r \ce{[A][B]} . Here, the rate of the reaction is proportional to the rate at which the reactants come together. An example of a bimolecular reaction is the S N 2-type nucleophilic substitution of methyl bromide by hydroxide ion: Morrison R.T. and Boyd R.N.
