Chemical Equilibrium

These flashcards cover key terms and concepts related to chemical equilibrium, including definitions and principles relevant to understanding the subject.

Chemical Equilibrium

A state where two opposing reactions occur simultaneously at the same rate.

Equilibrium Constant (Kc)

A value that expresses the ratio of the concentrations of products to reactants at equilibrium.

Dynamic Equilibrium

A type of equilibrium where molecules are continually reacting, but the overall composition remains constant.

Le Chatelier’s Principle

If a change in conditions is applied to a system in equilibrium, the system will respond to counteract the change.

The Reaction Quotient (Q)

An expression that measures the relative amounts of products and reactants at any point in time, not necessarily at equilibrium.

Heterogeneous Equilibria

Equilibria involving reactants and products in different phases.

Activity (in Chemistry)

A measure of the effective concentration of a species in a reaction, usually dimensionless.

Partial Pressure

The pressure exerted by a single component of a mixture of gases.

Relationship Between Kp and Kc

The relationship that connects the equilibrium constants for concentrations and partial pressures.

The Haber Process

An industrial method for synthesizing ammonia from nitrogen and hydrogen gases.
