Page 2: Chemical Kinetics

This section explores reaction rates and the factors affecting chemical reactions, with particular emphasis on reaction order and activation energy concepts.

Definition: Reaction rate is the change in concentration of reactants or products over time.

Highlight: The overall order of a reaction is the sum of individual orders with respect to each reactant.

Example: For a reaction aA + bB → products, the rate equation is v = k[A]ᵃ[B]ᵇ

Vocabulary:

Activation energy: Minimum energy required for a reaction to occur
Complex activated: Transition state during a chemical reaction

Ver

Page 3: Chemical Equilibrium Fundamentals

This page details the principles of chemical equilibrium, focusing on equilibrium constants and their relationships.

Definition: The equilibrium constant (Kc) represents the ratio of product concentrations to reactant concentrations at equilibrium.

Highlight: The relationship between Kp and Kc is given by Kp = Kc(RT)ᐩⁿ

Quote: "Le Chatelier's Principle states that when an equilibrium is disturbed, the system shifts to counteract the disturbance."

Vocabulary:

Equilibrium constant: Numerical value indicating the extent of reaction
Partial pressure: Pressure exerted by individual gas in a mixture

Ver

Page 4: Factors Affecting Chemical Equilibrium

This section examines various factors that influence chemical equilibrium and their effects on reaction systems.

Definition: The reaction quotient (Q) represents the ratio of products to reactants at any moment during a reaction.

Highlight: Temperature changes affect endothermic and exothermic reactions differently according to Le Chatelier's Principle.

Example: Increasing pressure shifts equilibrium toward fewer gas molecules.

Vocabulary:

Heterogeneous equilibrium: Equilibrium involving substances in different phases
Reaction quotient: Non-equilibrium ratio of products to reactants

Ver

Page 5: Solubility Equilibrium

This page covers solubility equilibrium concepts and calculations, focusing on solubility product constants.

Definition: The solubility product constant (Ks) is the product of the ionic concentrations raised to their stoichiometric coefficients.

Example: For a salt AxBy, Ks = [A]ˣ[B]ʸ

Highlight: Precipitation occurs when the ion product exceeds the solubility product constant.

Vocabulary:

Solubility: Maximum amount of solute that can dissolve in a solvent
Ion product: Product of ionic concentrations at any given moment

Page 1: Electrochemistry Fundamentals

This page introduces key concepts in electrochemistry, focusing on galvanic cells and electrolytic cells. The content explains the fundamental differences between spontaneous and non-spontaneous electrochemical reactions.

Definition: A galvanic cell is a device that produces electrical current from a spontaneous chemical reaction.

Highlight: The potential of a cell is calculated as the difference between reduction potential and oxidation potential.

Example: In a galvanic cell, oxidation occurs at the anode while reduction occurs at the cathode, generating electrical current.

Vocabulary:

Spontaneous reaction: Occurs naturally without external energy input
Electrolytic cell: Requires electrical energy to drive non-spontaneous reactions
