|The orientation aspect of collision theory, for the reaction NO3 + CO ⇌ NO2 + CO2, the idea that colliding molecules have to be aligned in a certain favorable way, during the instance of impact, in order for a reaction to occur or for the activation energy barrier to be surmounted. |
“You can’t react if you don’t collide.”
|Promo slogan (Ѻ) for the 2004 film Crash by Paul Haggis, giving an detailed look at "collisions" in the social sphere (see: social collision theory).|
See main: Social collision theoryIn human reaction terms, collision theory applies absolutely; however, the visual conception of collisions between human molecules, moving over substrate, requires a bit of discussion, as well as the development of new terminologies. In other words, collision theory was developed originally for reactions between atoms and molecules in the gas or liquid phase. Subsequently, applying it to human reactions occurring over substrate will require further development. In particular, a theory of human molecular reaction orbitals, i.e. probabilistic activity orbitals, describes collisions such that from a time-accelerated point of view, collisions of human probability orbitals, oriented in various unique energetic manners, will play a significant role in determining the outcome of basic human molecular collisions.
|The collision rate being inversely proportional to reactant concentration aspect of collision theory.|
|The activation energy aspect of collision theory: with a catalyst, reactions occur more easily, without catalyst only with more impact energy.|
