    Chemical reaction: 2A + B → unkwown product.

    Molecularity is the number of molecules that come together to react in an elementary (single-step) reaction and Molecularity in chemistry is the number of molecules that come together to react in an elementary (single-step) reaction and is equal to the sum of stoichiometric coefficients of reactants in this elementary reaction.

    This reaction is termolecular (or trimolecular) because three molecules react (two A and one B).
