⚠️ Common Misconceptions
Misconception 1: "All collisions lead to reactions"
This is wrong. Only successful collisions produce a reaction. Most collisions do not result in a reaction because either the energy is below the activation energy threshold, or the particles collide at the wrong angle. A faster rate means more successful collisions per second — not more collisions in general.
Misconception 2: "Activation energy is the energy of the particles"
Activation energy is not a property of individual particles — it is a property of the reaction itself. It represents the energy barrier that must be overcome to break bonds and start the reaction. Different reactions have different activation energies. Catalysts work by lowering this barrier, not by giving particles more energy.
Misconception 3: "Rate of reaction and amount of product are the same thing"
Rate refers to how fast the reaction proceeds. The final amount of product depends on how much reactant was present (the limiting reagent), not how fast it reacted. Two reactions with different rates can produce the same total amount of product if they start with the same reactants.
