Which mechanism impedes a reaction's rate in a high-energy collision between gas phase molecules?

💡 Explanation

Steric hindrance obstructs the reaction because bulky groups prevent proper alignment for bond formation, therefore lessening successful collisions, rather than the stabilization and bond alterations predicted by other answer options.
