Question 1.
What happens to the reaction rate when the surface area of a solid reactant is increased?
Show hintHide hint
Think about how many pieces a solid can become.
Question 2.
Give an example of a solid reactant that reacts faster when powdered.
Show hintHide hint
Consider the acid reaction example.
3Question 3.
How does increasing the surface area of a reactant affect the rate of reaction?
- It decreases the rate.
- It has no effect.
- It increases the rate.
Show hintHide hint
Think of how different shapes of the same material react.
4Question 4.
True or False: Smaller pieces of solids react slower than larger pieces.
- True
- False
Show hintHide hint
Consider the collision opportunities for each size.
Question 5.
If a solid reactant is crushed into a fine powder, how does this affect the overall reaction time in a real-life industrial process, such as in the manufacturing of cement?
Show hintHide hint
Consider the differences in contact between materials.
Question 6.
Propose a method for quantifying the speed of reaction with varying surface areas of solids, detailing measurements and data collection.
Show hintHide hint
Think about how you could visualize this comparison clearly.
