ORDER AND MOLECULARITY
==========================
ORDER
=======
=> the sum of the powers of the concentration terms in rate law expression
=> it is determined experimentally
=> it can be a whole number, zero or even fraction
=> provides some ideas about. Reaction mechanism
MOLECULARITY
==============
=> it is the number of reacting species undergoing simultaneous collision in the reaction
=> it is a theoretical concept
=> it always a whole number
=> does not tell us the reaction mechanism
