Collision Theory and Activation Energy | GCSE Chemistry
For a reaction to occur, particles must collide with enough energy to break bonds.
What is the minimum amount of energy needed for a reaction called?
What is Collision Theory and Activation Energy | GCSE Chemistry?
"The theory that chemical reactions occur when particles collide with sufficient energy and correct orientation."
Increasing the concentration of reactants increases the rate because particles...
Why does a powder react faster than a single large lump of the same mass?
How does a catalyst increase the rate of reaction?
Collision Essentials
Activation Energy ($E_a$): The minimum energy required for a successful collision.
Higher Temperature: Particles move faster and have more energy than $E_a$.
Successful Collisions: Those that result in a reaction.
Catalysts: Lower the activation energy required.
Exam Link: Always distinguish between "frequency of collisions" and "energy of collisions". Temperature affects both!
