Answer

Molecules must collide to react because collisions provide the energy and proper orientation needed for bond-breaking and bond-forming processes. Explanation 1. Explain collision theory According to collision theory, molecules must collide to react because a reaction occurs when reactants come into contact with sufficient energy and proper orientation. 2. Define activation energy Collisions provide the necessary energy (activation energy) to break bonds in reactants and form new bonds in products. 3. Emphasize orientation Proper molecular alignment during collisions ensures that reactive parts of molecules interact effectively.
