Thermodynamics: • Observe or measure temperature changes in chemical reactions and classify as endothermic or exothermic • Identify activation energy, endothermic, and exothermic reactions using an energy diagram Reaction Rates: • Correlate frequency and energy of collisions to reaction rate. • Identify factors that increase reaction rates (temperature, concentration, particle size/surface area, catalysts). Equilibrium: • Explain the concept of reversible reactions • Describe how dynamic equilibrium is affected by adding a product, reactant, or heat (Le Chatelier’s Principle) Electrochemistry: • Define reduction and oxidation in simple half reactions • Describe the direction of electron transfer in an electrochemical cell using an activity series.
