Examples

• The reaction proceeds bimolecularly when two reactant molecules collide simultaneously.
• In bimolecularly catalyzed reactions, the rate depends on the concentration of both reactants.
• The mechanism was determined to be bimolecularly controlled based on kinetic analysis.
• Bimolecularly initiated processes require precise molecular alignment for successful reaction.
