StandardHeatofFormation

• Print out and read/take notes on [Standard Heat of Formation]
• Read and take notes (or supplement notes from above website) on Zumdahl Section 6.4 (Pg257-265)
• Remember, the heat of reaction, deltaH_rxn = deltaH(products) - deltaH(reactants) {see Zumdahl Pg261 and/or see AP cheatsheet for equation w/apprpiate symbols}.
  • where deltaH(product)=sum of (coefficent moles of product)(standard heat of formation of product)for each product
    
  • where deltaH(reactant)=sum of (coefficent moles of reactant)(standard heat of formation of reactants)for each rectants
    • The standard heat of formation, deltaH_f^o, you find in a book and all elements in the phase they exist at 25degrees & 1atm is zero.
• See Zumdahl Pg264 (Sample Exercise 6.10) for steps of calculations.
