Chapter 6.5, Problem 6.15YT

Equation 6.10 represents the combustion of hydrogen; that is, the reaction of hydrogen and oxygen to produce water vapor. Equation 5.7 provided the Lewis structures for this chemical reaction. Using the bond energies for those bonds broken and formed, the energy change for this reaction can be estimated. As shown in Figure 5.8, the value is −498 kJ for burning two moles of H2.

  1. a. Calculate the energy change per mole and per gram of H2.
  2. b. Of the fuels listed in Figure 5.6, methane releases the most heat per gram upon combustion. Burning hydrogen releases even more heat. Approximately how many times more?
