Estimate the orders of magnitude of the partition functions involved in a rate expression. State the order of magnitude of for typical molecules. Check that in the collision of two structureless molecules the order of magnitude of the pre-exponential factor is of the same order as that predicted by collision theory. Go on to estimate the P factor for a reaction in which , and A and B are nonlinear triatomic molecules.
