Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
