Kinetics and Equilibrium Quiz Review

Collision Theory 1.

• Collision must involve enough energy to produce the
  reaction (must equal or exceed the activation energy, EA).

• Relative orientation of the reactants must
  allow formation of any new bonds necessary to
  produce products

• Often involves the formation of a transition state (or activated complex) – unstable species in equilibrium with reactants and products

Collision Theory #2

• Collision must involve enough energy to produce the
  reaction (must equal or exceed the activation energy, EA).

• Relative orientation of the reactants must
  allow formation of any new bonds necessary to
  produce products.

• Often involves the formation of a transition state (or activated complex) – unstable species in equilibrium with reactants and products

Collision Theory #3

• Often involves the formation of a transition state (or activated complex) – unstable species in equilibrium with reactants and products

• Relative orientation of the reactants must
  allow formation of any new bonds necessary to
  produce products.

• Collision must involve enough energy to produce the
  reaction (must equal or exceed the activation energy, EA).

Reaction Mechanism- Most chemical reactions occur by a series of...

• Elementary reactions

• Intermediate Reactions

• Reactions with higher activation energy

• Kinetically stable Reactions

Reaction Mechanism- An ____ is formed in one step and used up in a
subsequent step and thus is never seen as a product in
the overall balanced reaction.

• Thermodynamic Reaction

• 
  Intermediate

• Elementary Reaction

• Chemical Reaction

Reaction Mechanism Requirements

• Reaction Mechanisms require high temperature to occur.

• The sum of the elementary steps must give the
  overall balanced equation for the reaction.

• The mechanism must agree with the experimentally
  determined rate law.

• A reaction mechanism must always involve a catalyst.
