Course Description

This course introduces students to foundational concepts in physical chemistry, focusing on the energetic behavior of matter and its changes. Topics include thermodynamics, intermolecular forces, chemical kinetics, equilibrium, entropy, and electrochemistry. The course emphasizes the importance of understanding energy changes and chemical reactivity, providing a basis for advanced study in chemistry and related fields.

Course Learning Outcomes

Upon completion of CHEM 1110, students should be able to:

• Explain the effects of intermolecular forces on physical properties and phase changes.

• Apply thermodynamic principles to chemical processes.

• Predict the direction and extent of chemical reactions using entropy and Gibbs energy.

• Analyze chemical equilibria, including acid-base and solubility equilibria.

• Describe the principles of chemical kinetics and reaction mechanisms.

• Understand and apply concepts of electrochemistry, including redox reactions and cell potentials.

Course Topics and Key Concepts

Part 1: Intermolecular Forces

Intermolecular forces are the interactions between molecules that influence physical properties such as boiling point, melting point, and solubility.

• Types of Intermolecular Forces: London dispersion, dipole-dipole, hydrogen bonding.

• Effects on Properties: Influence condensation, vaporization, and melting.

• Examples: Water's high boiling point due to hydrogen bonding.

Part 2: Spontaneity of Chemical Processes

Spontaneity refers to whether a chemical process occurs naturally without external intervention. It is determined by changes in entropy and Gibbs free energy.

• Entropy ($S$): Measure of disorder in a system.

• Gibbs Free Energy ($G$): $G = H - TS$ (where $H$ is enthalpy, $T$ is temperature, $S$ is entropy).

• Spontaneous Process: Occurs when $riangle G < 0$.

• Example: Ice melting at room temperature.

Part 3: Chemical Kinetics

Chemical kinetics studies the rates of chemical reactions and the factors that affect them.

• Rate of Reaction: Change in concentration of reactants/products per unit time.

• Rate Law: $ext{Rate} = k[ ext{A}]^m[ ext{B}]^n$

• Activation Energy: Minimum energy required for a reaction to occur.

• Example: Decomposition of hydrogen peroxide catalyzed by manganese dioxide.

Part 4: Chemical Equilibrium

Chemical equilibrium occurs when the rates of the forward and reverse reactions are equal, resulting in constant concentrations of reactants and products.

• Equilibrium Constant ($K$): $K = rac{[ ext{products}]}{[ ext{reactants}]}$

• Le Châtelier's Principle: System shifts to counteract changes in concentration, pressure, or temperature.

• Example: Dissociation of acetic acid in water.

Part 5: Electrochemistry

Electrochemistry involves the study of chemical processes that involve electron transfer, including redox reactions and the operation of electrochemical cells.

• Redox Reaction: Transfer of electrons between species.

• Cell Potential ($E_{cell}$): $E_{cell} = E_{cathode} - E_{anode}$

• Galvanic Cell: Device that converts chemical energy into electrical energy.

• Example: Zinc-copper voltaic cell.

Supplementary Topics from CHEM 1100 (Review)

• Energy and Thermodynamics: First law ($riangle E = q + w$), heat, work, enthalpy.

• Atomic Structure and Light: Quantum numbers, electron configuration, periodic trends.

• Chemical Bonding: Covalent and ionic bonds, Lewis structures, resonance.

• Periodic Properties: Atomic radius, ionization energy, electron affinity.

Sample Table: Types of Intermolecular Forces and Their Effects

Type of Force	Example	Effect on Properties
London Dispersion	Argon, Methane	Low boiling/melting points
Dipole-Dipole	Acetone	Moderate boiling/melting points
Hydrogen Bonding	Water, Ammonia	High boiling/melting points

Key Equations

• Gibbs Free Energy: $\triangle G = \triangle H - T \triangle S$

• Rate Law: $\text{Rate} = k[\text{A}]^m[\text{B}]^n$

• Equilibrium Constant: $K = \frac{[\text{products}]}{[\text{reactants}]}$

• Cell Potential: $E_{cell} = E_{cathode} - E_{anode}$
