Featured Formulas

1. Gibbs Free Energy

$\Delta G = \Delta H - T\Delta S$

• Application: Predict reaction spontaneity.
• Example: If ( \Delta H = -100 ) kJ/mol, ( \Delta S = 0.2 ) kJ/(mol·K), T = 298 K, calculate ( \Delta G ). Answer: ( -100 - (298 \times 0.2) = -159.6 ) kJ/mol.

2. Nernst Equation

$E = E^0 - \frac{RT}{nF} \ln Q$

• Application: Calculate cell potentials.
• Example: For ( E^0 = 0.76 ) V, n = 2, Q = 0.01, T = 298 K, calculate ( E ).

3. Equilibrium Constant

$K = \frac{[Products]}{[Reactants]}$

• Application: Analyze equilibrium systems.
• Example: Calculate ( K ) for a reaction with given concentrations.

Study Tips

• Focus on AP Topics: Prioritize thermodynamics, electrochemistry, and equilibrium.
• Practice Problems: Use AP-style questions to apply formulas.
• Memorize Constants: Know values like ( R = 8.314 ) J/(mol·K).
