SUMMARY

The discussion centers on the concept of steric factors in chemical reactions, specifically addressing scenarios where steric factors exceed 1. Participants clarify that this phenomenon occurs due to the influence of transition states and the specific geometries of reactants, which can enhance reaction rates beyond simple collision theory predictions. The conversation highlights that steric factors greater than 1 indicate favorable orientations and interactions that facilitate reactions more efficiently than expected.

I noticed in my book, some reactions have a steric factor greater than 1. How is this possible? I thought reactions were collision limited and orientation can only limit reaction rate.
