Specifically relates to molecular collision; Deals with the frequency of molecules that collide in the correct orientation and with enough energy to initiate a reaction.
Measurement of frequency can be done in the following ways: Calculating the frequency of a repeating event is accomplished by counting the number of times that event occurs within a specific time period, then dividing the count by the period. For example, if 71 events occur within 15 seconds the frequency is:
