Electron transfers and these processes occur faster than expected in a harpoon reaction. These processes occur between A and A-star in the Lindemann mechanism. The rate of these processes can be calculated as the square root of [read slowly] “eight times k B T, divided by the product of pi and the reduced mass” times sigma. The frequency of these processes times a (*) steric factor gives the (10[1])Arrhenius (10[4])pre-exponential factor. Velocity does not correlate to (10[1])the time between these processes, during which a molecule will travel one mean (10[2])free path. The ideal gas law can be derived by defining pressure as the force (10[1])of these events, which are “effective” when they occur at proper orientations. For 10 points, name these events that kinetic molecular theory assumes are elastic. ■END■
