,Specification
, Kinetics-> Collision theory
-Reactions occur when particles collide with an energy greater or equal to the activation energy (Ae)
-Many collisions occur but only a few are successful
Define activation energy: The minimum energy required for a reaction to take place
-Conditions that affects the reaction: temperature, catalyst, pressure.
Common MS answers:
(1)increases the no. of collisions
(2) increases the no. of successful collisions per second
(3)more molecules with energy greater than activation energy(Ae)
(4) Rate of reaction increases
