Question 1.
Define heterogeneous catalysis.
Show hintHide hint
Think about the phases of matter.
Question 2.
What is the role of a catalyst in a reaction?
Show hintHide hint
Consider how a catalyst affects reaction rates.
3Question 3.
What is the main characteristic of heterogeneous catalysis?
- Both catalyst and reactants are in the same phase.
- The catalyst is in a different phase from the reactants.
- Heterogeneous catalysis does not exist.
Show hintHide hint
Think of solids acting with gases.
4Question 4.
True or False: In heterogeneous catalysis, the catalyst is consumed during the reaction.
- True
- False
Show hintHide hint
Consider the role of catalysts.
Question 5.
Given a scenario where a car's catalytic converter is malfunctioning, describe how this might affect the vehicle's emission levels and relate it to the principles of heterogeneous catalysis.
Show hintHide hint
Consider what reactions are supposed to occur in a catalytic converter.
Question 6.
Design an experiment to test the effectiveness of different catalysts in the decomposition of hydrogen peroxide. Discuss the role of surface area and catalyst type in your design.
Show hintHide hint
Think about how you can control variables like catalyst surface area.
