Review Key

Learning Objectives

• Thermochemistry
  • Distinguish exothermic and endothermic processes based on movement of energy
  • Describe the relationship between temperature and states of matter as outlined by warming (cooling) curves
  • Calculate heat changes for changes in temperature and states of matter using enthalpy equations
• Reaction Rates
  • Use collision theory to describe how chemical reactions are based on the motion and arrangement of reactant particles
  • Identify factors that affect reaction rates: temperature, concentration, surface area and catalysts
  • Interpret an energy diagram for a reaction
• Chemical Equilibrium
  • Describe a system in equilibrium using equilibrium chemical equations
  • Write an equilibrium expression for a system in equilibrium (K_eq)
  • Using Le Châtelier’s principle, describe the shift that results from changes in concentration, temperature, or pressure of a system in equilibrium
