Question 1.
Define Activation Energy.
Show hintHide hint
Think about what energy is needed for molecules to react.
Question 2.
What is a Steric Factor?
Show hintHide hint
Consider collisions that lead to an actual reaction.
3Question 3.
What two conditions must be met for a collision to be effective?
- Sufficient energy and correct orientation
- Sufficient energy only
- Correct orientation only
Show hintHide hint
Think about what happens if either condition is missing.
4Question 4.
True or False: All collisions between molecules result in a chemical reaction.
- True
- False
Show hintHide hint
Remember the criteria for effective collisions.
Question 5.
If the collision frequency (Z_AB) of two gas molecules is 250 collisions/s with a steric factor (p) of 0.15, what is the effectiveness of their collisions?
Show hintHide hint
Multiply the total number of collisions by the steric factor.
Question 6.
Describe how increasing temperature could qualitatively affect reaction rates in a detailed reaction mechanism involving catalysts.
Show hintHide hint
Consider the rates of collisions and energy distribution at higher temperatures.
