Based on collision theory, the rate of a chemical reaction can be given as ZAB.e-Ea/RT.
ZAB represents the collision frequency of reactants, A and B
- Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation.
- In the reaction A + B → ABThe rate of the reaction is equal to the number of active collisions. So the rate of reaction can be written as
Ea: is the activation energy (J/mol)
