Answer
a) Elementary step: reaction whose rate law can be expressed in terms of its molecularity
b) Molecularity: number of different atoms that must come together for the reaction to take place.
c) Reaction mechanism: series of elementary steps by which the overall reaction takes place.
d) Intermediate: species formed and consumed during the overall reaction process
e) Rate-determining step: slowest step in the reaction mechanism which determines the overall reaction rate
