Chemistry Kinetics Review

Flashcards covering key concepts in kinetics relating to reaction rates and rate laws.

Average Rate of Reaction

The change in concentration of a reactant or product over a given time interval.

Instantaneous Rate of Reaction

The reaction rate at a specific point in time, determined by the slope of the tangent at that point.

Differential Rate Law

A mathematical expression that relates initial reactant concentration to reaction rate; derived from varying initial concentrations.

Integrated Rate Law

An equation that relates the concentration of a reactant to time, determined by measuring concentration at regular time intervals.

Secant

A line drawn between two points on a curve, used to find the average rate of change.

Tangent

A line that just touches a curve at a point, used to find the instantaneous rate of change.

Spectrophotometer

An instrument used to measure the change in color intensity to indicate a change in concentration.

Reaction Rate

A measure of the change in concentration of reactants or products as a chemical reaction progresses over time.

Stoichiometry

The quantitative relationship between reactants and products in a chemical reaction.

Conductivity

A property indicating the concentration of ions in a solution, which can change during a reaction.

Negative Slope

Indicates a decrease in concentration of a reactant over time.

Positive Slope

Indicates an increase in concentration of a product over time.
