Thermochemistry: The Study of Heat in Chemical Reactions
  • Thermochemistry: The Study of Heat in Chemical Reactions

  • Summary • 15 pages • 2024
  • Delve into the fascinating world of thermochemistry, where we explore how heat is involved in chemical reactions and changes in state. This section covers the principles of heat transfer, enthalpy changes, and calorimetry. Learn to calculate reaction heat changes, understand exothermic and endothermic processes, and apply Hess's Law to determine reaction energies. We will also discuss the relationship between thermochemistry and reaction spontaneity, providing insights into the energetic aspect...
