Reaction Profiles Requirements
Chemistry: AQA GCSE Higher, topic 5.1.5
Requirements for a Reaction to Happen
There are 2 main requirements for a successful reaction to take place:
Collisions
- Particles of the reactants have to collide.
Activation energy
- The collisions that happen between particles of the reactants must take place with enough energy.
- This threshold amount of energy is called the activation energy.
Test yourself on Reaction Profiles Requirements
A molecule of ethane collides with a molecule of iodine, but with less energy than the activation energy. What happens to the reaction between them?
A molecule of ethane collides with a molecule of iodine with more energy than the activation energy. What happens to the reaction between them?
