Chemical Kinetics and Reaction Mechanisms

Chemical Kinetics

Study of reaction rates and mechanisms.

Stoichiometric Number

Coefficient indicating the amount of a species.

Reaction Coordinate

Variable representing the extent of reaction progress.

Mole Fraction

Ratio of a component's moles to total moles.

Inert Species

Species that does not participate in the reaction.

Collision Theory

Reactions require collisions with sufficient energy.

Activation Energy (Ea)

Minimum energy required for a reaction to occur.

Catalyst

Substance that increases reaction rate without consumption.

Factors Affecting Reaction Rate

Temperature, concentration, surface area, and catalysts.

Temperature Effect

Higher temperatures increase kinetic energy and collisions.

Concentration Effect

Higher concentration increases likelihood of collisions.

Surface Area Effect

Greater surface area allows more contact between reactants.

Multi-Reaction Stoichiometry

Analysis of multiple reactions occurring simultaneously.

Extent of Reaction

Measure of how far a reaction has progressed.

Reaction Index (j)

Identifier for specific reactions in multi-reaction systems.

Chemical Synthesis

Transformation of raw materials into valuable products.

Kinetics Information

Insights into speed and mechanism of reactions.

Reaction Completion

Point at which reactants are fully converted to products.

Mole Balance

Conservation of moles in chemical reactions.

Chemical Equilibrium

State where reactants and products are in balance.

Reaction Mechanism

Detailed steps through which a reaction proceeds.

Proportional Changes

Changes in moles relate directly to stoichiometric numbers.

Reaction Progress Variable (ε)

Single variable indicating the extent of reaction.

Reaction Yield

Amount of product formed from a reaction.

Kinetic Energy

Energy of motion affecting reaction rates.

Chemical Reaction Rates

Speed at which reactants convert to products.
