Transition State Theory

Can someone explain to me what the transition state theory is, and how it differs from the collision theory? Thank you!

Re: Transition State Theory

In transition state theory (TST) an activated molecule is formed during the reaction at the transition state between forming products from reactant.This differs from collision theory because collision theory applies only to gas phase reactions while transition state theory is a generalization to reactions in solution.

Re: Transition State Theory

Transition state theory deals with all reactions, while collision theory applies only to reactions in the gas phase because all other phases are colliding much more frequently.

Re: Transition State Theory

The transition state theory states there exists a state between the reactants and products where the compound is in its highest energy form called the activated complex. This is different from the collision theory as it states that the more frequent collisions the reactants go through the faster the rate of the reaction will end up being.
