Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a reaction between two gases where the steric factor is significantly reduced due to the size of the molecules. Discuss how this would affect the overall rate of reaction at different temperatures.

💡 Hint: Focus on how temperature and orientation impact reaction rates in conjunction.

Challenge 2 Hard

Design an experiment to determine the steric factor for two different reaction mechanisms. What approaches would you take, and what data would you need?

💡 Hint: Think about varying conditions and reaction parameters!
