Thermochemistry Essentials

Thermochemistry deals with heat changes in chemical reactions. Here are the most important equations:

• Hess’s Law: ΔH°_rxn = ΣΔH°_f(products) - ΣΔH°_f(reactants)
• Enthalpy Change (q): q = mcΔT

📌 Note: Always ensure units are consistent when using these formulas, AP Chem Thermochemistry, Hess’s Law Explained.

Gases and Gas Laws

Understanding gas behavior is fundamental in AP Chemistry. Key equations include:

• Ideal Gas Law: PV = nRT
• Combined Gas Law: (P₁V₁)/T₁ = (P₂V₂)/T₂

📌 Note: The Ideal Gas Law is the most versatile and commonly used, Ideal Gas Law Applications, Gas Laws Simplified.

Equilibrium Constants

Equilibrium constants are vital for understanding reaction dynamics. Key formulas include:

• Kc Expression: Kc = [C]^c[D]^d / [A]^a[B]^b
• Kp Expression: Kp = (P_C)^c(P_D)^d / (P_A)^a(P_B)^b

📌 Note: Ensure you know whether to use Kc or Kp based on the phase of the substances, Equilibrium Constants Explained, AP Chem Equilibrium.

Acid-Base Chemistry

Acid-base reactions are a cornerstone of AP Chemistry. Important equations include:

• pH Calculation: pH = -log[H⁺]
• Henderson-Hasselbalch Equation: pH = pKa + log([A^-]/[HA])

📌 Note: The Henderson-Hasselbalch equation is particularly useful for buffer solutions, Acid-Base Reactions, pH Calculations.
