The number of molecules that react with ...

The number of molecules that react with each in an elementary step gives a measure of the

A

order of the reaction

B

molecularity of the reaction

C

stoichiometry of the reaction

D

activation energy of the reaction

Text Solution

Verified by Experts

The correct Answer is:
B
Elementary reactions are classfied according to their molecularity. The number of reacting species (atoms, molecules or ions) taking part in an elementary reaction, which must colllide simultaneously in order to bring about a chemical reaction is called molecularity of a reaction.
