Question 1.
What is the basic requirement for a reaction to occur according to collision theory?
Show hintHide hint
Think about what has to happen before the actual reaction.
Question 2.
Name one factor that affects reaction rates.
Show hintHide hint
Consider how changes in conditions might impact a reaction.
3Question 3.
What is one of the essential conditions for a successful chemical reaction?
- Particles must collide
- Temperature cannot change
- Only one particle required
Show hintHide hint
Recall the very first requirement discussed in class for reactions.
4Question 4.
True or False: A catalyst gets consumed during a reaction.
- True
- False
Show hintHide hint
Think about the definition and purpose of a catalyst.
Question 5.
A reaction has an activation energy of 50 kJ/mol. If the temperature is increased from 300 K to 400 K, what effect would you expect on the reaction rate and why?
Show hintHide hint
Think about how temperature affects particle kinetic energy.
Question 6.
Give an example of a situation in baking where increasing surface area leads to a faster reaction rate and explain how it works.
Show hintHide hint
Consider how smaller pieces compared to whole items change reactivity.
