This unit explores how energy is transferred as heat during chemical processes and whether reactions occur spontaneously. 1. Key Theoretical Concepts Systems and Energy: Difference between open, closed, and isolated systems. First Law of Thermodynamics: The conservation of energy in chemical processes ( Enthalpy ( Calculation of reaction enthalpy ( ) using standard enthalpies of formation. Hess's Law: A critical method for calculating using intermediate steps. ) and Spontaneity: Understanding disorder and the Second Law of Thermodynamics Gibbs Free Energy ( Determining reaction spontaneity using 2. Common Problem Types (Solved in the Solucionario) Hess's Law Problems:
