Kinetics and Collision Theory

A set of vocabulary flashcards covering key concepts from the topic of kinetics and collision theory.

Collision Theory

Explains how and why chemical reactions occur based on particle collisions.

Effective Collisions

Collisions between particles that lead to the formation of products.

Ineffective Collisions

Collisions that do not result in a chemical reaction.

Transition State

A short-lived, high energy state during which bonds are both broken and formed.

Activated Complex

A complex that forms during the transition state of a chemical reaction.

Activation Energy

The minimum energy required to result in an effective collision.

Factors Affecting Reaction Rate

Factors such as surface area, temperature, concentration, catalyst, and nature of reactants.

Surface Area

The extent to which reactants are exposed, influencing collision frequency.

Temperature

Higher temperatures increase particle movement and collision frequency.

Concentration

The amount of reactants present influencing the rate of effective collisions.

Catalyst

A substance that provides an alternate pathway with lower activation energy.

Nature of Reactants

Different reactants have different activation energies and reactivity.
