Probability of higher order reactions

Postby Alexia_Vanegas_1G » Mon Feb 13, 2017 1:12 pm

If the temperature of a reaction, or any other outside factor, like pressure, is increased, can higher order reactions of molecules colliding simultaneously more probable/likely to occur?

Increasing the temperature and the pressure will increase the kinetic energy of the molecules, which will increase the number of collisions happening over a certain period of time. As the overall number of collisions increases, the number of rare collisions (tetra or trimolecular) will also increase. However, the increase is still proportional. You're not going to see a situation where it's more likely to have a tetramolecular collision than a bimolecular one
