To alleviate this problem, a new concept must be introduced: the steric factor ρ. It is defined as the ratio between the experimental value and the predicted one (or the ratio between the frequency factor and the collision frequency): =,
The steric factor, usually denoted ρ, [1] is a quantity used in collision theory. Also called the probability factor , the steric factor is defined as the ratio between the experimental value of the rate constant and the one predicted by collision theory.
Collision frequency describes the rate of collisions between two atomic or molecular species in a given volume, per unit time. In an ideal gas , assuming that the species behave like hard spheres, the collision frequency between entities of species A and species B is: [ 1 ]
It is considered to be one of the most devastating human-caused environmental disasters ever to occur in history. [ 21 ] 100,000 to as many as 250,000 seabirds died as well as at least 2,800 sea otters , approximately 12 river otters , 300 harbor seals , 247 bald eagles , and 22 orcas , and billions of salmon and herring eggs were destroyed.

Elastic collisions with the mercury atoms increase the time it takes for an electron to arrive at the grid, but the average kinetic energy of electrons arriving there isn't much affected. [ 17 ] When the grid voltage reaches 4.9 V, electron collisions near the grid become inelastic, and the electrons are greatly slowed.
A number of factors, both technological and human-driven, could have played a role in the deadly accident, aviation experts say, including whether multilayered systems designed to stop collisions ...
The total number of collisions in 2016 exceeded the number from Run 1 – at a higher energy per collision. The proton–proton run was followed by four weeks of proton–lead collisions. [109] In 2017, the luminosity was increased further and reached twice the design value. The total number of collisions was higher than in 2016 as well. [41]
