The exact nature of this type of reaction is often difficult to assess, in collision theory a simultaneous interaction of 3 or more different molecules is less likely resulting in a low reaction rate.

The collision theory states that when suitable particles of the reactant hit each other, only a certain percentage of the collisions cause any noticeable or significant chemical change; these successful changes are called successful collisions.
33.
Both the United States and Britain, which had their submarines in the Barents Sea, have denied involvement, and most independent specialists dismissed the collision theory and pointed at a torpedo malfunction as the most plausible cause.
34.
The collision theory was ridiculed by many specialists, who pointed out that a foreign submarine wouldn't have been able to limp away from a collision with the much heavier, 18, 000-ton Kursk, one of the world's largest submarines.

He is also the author of hundred and forty-seven research articles and forty-five review articles in theoretical physics, devoted mainly to quantum collision theory with applications to atomic, nuclear and high-energy processes and to the theory of high-intensity laser-atom interactions.

This model was made assuming Quaoar actually had a density of 4.2 g / cm 3, but more-recent estimates have given it a more Pluto-like density of only 2 g / cm 3, with no more need for the collision theory.
37.
The United States and Britain, which had its submarines shadowing the Russian exercise, have denied their involvement and most experts ridiculed the collision theory saying that a Western submarine wouldn't have been able to limp away after colliding with the much heavier Kursk.

By the time the meeting ended, the bulk of lunar scientists had switched allegiance to the collision theory, says Wilhelms, whose 477-page book " To A Rocky Moon "-- a history of lunar geology-- was recently published by the University of Arizona Press.
39.
But a painstaking search of miles of seabed this fall turned up no such debris, and the official in charge of the Kursk recovery and investigation, deputy prime minister Ilya Klebanov, said recently that the collision theory was no more likely than any other.

At the beginning of the meeting, Salinger turned over his evidence of a government conspiracy to the agents : a copy of the original Internet posting by the Florida retiree, and printouts of the B-2 collision theory that he and his son had found.
