OCW Scholar

« Previous | Next »

Topics

 
  1. Thermodynamics
    1. Bond Energy / Bond Enthalpy (∆HB)
    2. Enthalpies of Reaction (∆Hr)
    3. Methods to Calculate ∆Hr

Lecture Video

Thermodynamics is key to understanding the reactivity of molecules and compounds. In this first of three lectures on thermodynamics, viewers are introduced to ∆H, and asked to consider how much heat it will take to break one type of molecular bond versus another. Viewers are also asked whether a particular chemical reaction will release heat or absorb heat.
