- OGS.11.PS.EQ.1Analyze energy changes in chemical reactions, construct reaction profiles showing activation energy and enthalpy changes (ΔH), calculate enthalpy using bond energies and Hess's Law, and apply entropy to assess thermodynamic feasibility.
- OGS.11.PS.EQ.2Apply collision theory and the Maxwell-Boltzmann distribution to explain factors affecting reaction rates (temperature, concentration, surface area, pressure, catalysts), and determine rate equations and reaction orders experimentally.
- OGS.11.PS.EQ.3Explain dynamic chemical equilibrium in reversible reactions, predict shifts using Le Chatelier's Principle, write equilibrium expressions, and calculate equilibrium constants (Kc, Kp).
- OGS.11.PS.EQ.4Model acid-base systems using Bronsted-Lowry theory, identify conjugate pairs, calculate pH, pOH, Kw, Ka, Kb, and Ks, analyze buffer solutions, perform volumetric titrations, and describe trends in oxyacid and hydrohalic acid strengths.
