2. Define 'Activation energy'
- The minimum energy required for a reaction to occur when particles collide
- The maximum energy required for a reaction to occur when particles collide
- Energy created during a reaction where particles collide
3. What factors increase rate of reaction by causing more frequent collisions per unit of time?
- concentration,pressure and surface area
- time, concentration and surface area
- surface area only
4. What is a 'successful' particle collision?
- collision that exceeds the activation energy
- collision that doesnt affect reaction rate
- collision that produces more product
5. What is the definition of a catalyst?
- Substance that causes an increased yield of product in a reaction.
- Substance that increases reaction rate, but is chemically unchanged at the end of the reaction
- Substance that increases reaction rate, but is chemically changed at the end of a reaction
