   Collision Theory (CT)
   Collision Theory (CT) models reactions in the gas phase as the result of direct molecular collisions. It posits that the rate is proportional to the frequency of collisions and the fraction of those collisions possessing sufficient energy ($E_a$) and the correct orientation. The frequency of collisions ($\text{Z}$) can be calculated using [hard-sphere molecular models](/entries/h…
