Problem 5 (10 points). In class we discuss collision theory by thinking about bimolecular reactions, e.g. A +BC in the gas phase. For hard spheres, if we instead had a reaction A+B+CD, what can you say about how this reaction may most likely proceed? For example, would the probability, or frequency, of a trimolecular collision ( A and B and C all colliding together at once) be higher than a bimolecular reaction? Make your arguments for your proposed reaction model using some sort of quantitative statement about the relative frequencies for bimolecular vs. trimolecular collisions. Assume the impact radius of the molecules is 3 Angstroms, and the MW is 15g/mol
