Challenge Problems
Push your limits with challenges.
Question 1
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?
💡 Hint: Multiply the total number of collisions by the steric factor.
Question 2
Describe how increasing temperature could qualitatively affect reaction rates in a detailed reaction mechanism involving catalysts.
💡 Hint: Consider the rates of collisions and energy distribution at higher temperatures.
