Other questions in this quiz
2. How does surface area affect the rate of reaction?
- The size of the particles means that they have more exposed sides.
- The particles need less activation energy to react.
- There are more particles to collide with each other.
- The particles move faster.
3. What does a catalyst do?
- Speed up the reaction without being used up itself.
- Make the particles move faster.
- Double the reaction time in the experiment.
- Increase surface area by breaking the particles into smaller pieces.
4. The collision theory is...
- When molecules collide the bonds between their atoms break and new bonds can form to make new molecules
- The amount of time it takes for all of the particles in the experiment to collide.
- When the molecules collide and dissolve each other so that only one chemical is left in the experiment.
- When the meteor crashed to earth and killed all the dinosaurs.
5. How does temperature affect the rate of reaction?
- There are more particles to collide with each other.
- It speeds up the movement of the particles.
- It breaks the particles into smaller pieces.
- The particles need less energy.
