Questions using effective collision
Problem 1
According to collision theory, an effective collision requires…
- enough energy and the correct orientation
- that a catalyst be present
- that the reaction be exothermic
- only that the particles touch
Answer and explanation
enough energy and the correct orientation
A collision only produces a reaction if the particles collide with at least the activation energy and are properly oriented.
