Chem 114 Final Exam Review

DISCLAIMER: This guide is not comprehensive. Even if something is not listed here, it might still be on the final. This is just a guide.

1 General strategies

  • This guide is not comprehensive
  • Look over past exams and quizzes; learn from your mistakes
  • Key Concepts and Key Equations in each chapter

2 Ch 6 - Thermodynamics

  • Heat capacities
    • Specific heat \(q=m\times C_s \times \Delta T\)
    • Molar heat \(q=m\times C_s \times \Delta T\)
    • Adiabatic (\(q_{total}=0\))
  • Work
  • Enthalpy
    • Endothermic vs exothermic
    • Hess' law
    • Formation reactions/enthalpy of formation
  • First law of thermodynamics
  • Phase changes (enthalpy of vaporization, etc) => ch 11

3 Ch 17 - Free Energy and Thermodynamics

  • Definition of entropy
    • \(S = k\ ln(W)\)
  • \(\Delta S_{univ} = \Delta S_{sys} + \Delta S_{surr}\)
  • \(\Delta S_{surr} = \frac{-\Delta H_{sys}}{T}\)
  • Gibbs' free energy
    • \(\Delta G = \Delta H-T\Delta S\)
    • Spontaneous vs non-spontaneous
    • \(\Delta G_{rxn} = \Delta G_{rxn}^{\circ} + RT\ ln(Q)\)
    • \(\Delta G\) at equilibrium
  • Second and third laws of thermodynamics
  • \(ln (K) = -\frac{\Delta H^{\circ}_{rxn}}{R}(\frac{1}{T}) + \frac{\Delta S^{\circ}_{rxn}}{R}\)

4 Ch 18 - Electrochemistry

  • Balancing redox reactions
  • Galvanic and electrolytic cells
    • Anode vs cathode
  • Standard reduction potentials
    • \(E^{\circ}_{cell} = E^{\circ}_{cathode} - E^{\circ}_{anode}\)
  • Nernst equation
    • \(E_{cell} = E^{\circ}_{cell} - \frac{0.0592}{n} log(Q)\)
    • What happens at equilibrium?

5 Ch 13 - Kinetics

  • Rate laws (zero-, first- and second-order)
    • Integrated rate laws
  • Half-life
  • Arrhenius equation
    • \(ln(k) = -\frac{E_a}{R}(\frac{1}{T}) + ln(A)\)
  • Mechanisms
    • Combining rate laws
    • Reaction diagrams
      • \(E_a\) vs \(\Delta H\)

6 Ch 7 - Quantum

  • DeBroglie wavelength
  • \(E = h\nu = \frac{hc}{\lambda}\)

  • Bohr model and equation
  • Quantum numbers
    • n, l, ml, ms
    • Atomic orbital shapes (s, p, d, f)

7 Ch 8 - Period properties and electron configurations

  • Periodic trends
  • Electron configurations

8 Ch 9 - Lewis Bonding

  • Lewis structures

10 Ch 24 - Coordination Chemistry

  • Metal oxidation states
  • d-electron count
