* Arrhenius law
 
 
<math>k = \mathcal{A} T^{\beta} \exp \left(-\frac{E_a}{R T}\right) </math>
 
 
 
The global rate of a reaction (evolution in concentration per unit of time) varies depending on the proportion of the rates associated to the forward and backward directions.
 
 
<math>
 
\mathcal{Q} = \mathcal{Q}_f - \mathcal{Q}_r
 
</math>
 
 
 
<math>
 
\dot{\omega}_k = W_k \sum_{j=1}^{N_R} \nu_{k,j} \mathcal{Q}_j
 
</math>
 
 
* Three-body reactions
 
 
In the forward direction, three-body reactions involve two species A and B as reactants and yield a single product AB. In that case, the third body M is used to stabilize the excited product AB*. On the contrary, in the reverse direction, heat provides the energy necessary to break the link between A and B.
 
 
<math>......</math>
 
 
The third body M can be any inert molecule.
