Cheat Sheet
- Gibbs Free Energy and Spontaneity -
Mastering ΔG = ΔH - TΔS is essential for tackling the hardest chemistry question on reaction spontaneity (NIST). Practice calculating Gibbs free energy changes at different temperatures and use the mnemonic "Gotta Have Some Temperature" to recall G = H - TS. Understanding how ΔG sign predicts equilibrium will help you ace difficult chemistry problems in real-world scenarios.
- Chemical Kinetics and Rate Laws -
Derive rate laws from experimental data and apply the method of initial rates to determine reaction order, a key skill in any chemistry practice test (ACS Resources). Remember the mnemonic "Zero, First, Second - ZFS" to keep rate law forms straight. Work through sample problems calculating half-lives for first-order and second-order reactions to build confidence.
- Equilibrium Concepts and Le Châtelier's Principle -
Understand Kc and Kp expressions and how changes in concentration, pressure, or temperature shift equilibria (MIT OpenCourseWare). Flashcards are great for memorizing how adding reactants or increasing temperature affects endothermic vs. exothermic systems. Being fluent in equilibrium calculations is crucial for tough chemistry questions on shift predictions.
- Acid-Base Titration Curves -
Analyze pH changes during titration of strong/weak acids and bases using the Henderson-Hasselbalch equation (Khan Academy). Plotting titration curves and identifying equivalence points will prepare you for trivia chemistry quiz items on buffer regions. Try practice problems adjusting Ka or Kb values to see how curve shape varies.
- Organic Reaction Mechanisms -
Distinguish SN1 vs. SN2 pathways by examining nucleophile strength, substrate structure, and solvent effects (IUPAC Guidelines). Use the "Backside Attack" mental image for SN2 and the "Carbocation Stability Ladder" for SN1 to recall key features quickly. Applying these patterns solves many of the most difficult chemistry problems in organic synthesis.
