Chemistry Chapter 10 pt 2

  1. Enthalpy (△H)
    • state function 
    • heat of rxn at a CONSTANT pressure 

    • △H = qp
    • △U = qr
  2. △Hrxn = Hproduct - Hreactant
    △H = -, exothermic

    △H = +, endothermic
  3. Thermochemical Reaction
    That thing where you multiply moles of a substance x △H
  4. Calorimetry
    q = ms△t

    qsys = -qsurr
  5. Hess's Law
    △H
  6. Bond Enthalpy (covalent molecules)
    Breaking a covalent bond REQUIRES energy (endothermic)

    Forming a covalent bond RELEASES energy (exothermic)
  7. Bond Enthalpy
    enthalpy associated with breaking a bond of 1 mole of a gaseous molecule
