Which of the following reactions is most likely to be exothermic?(a) F2(g) → 2 F(g) (b) 2 Cl(g) → Cl2(g) (c) Cu(s) → Cu(l) (d) CBr4(g) → C(g) + 4 Br(g) (e) CO(g) → C(g) + O(g)
The lead-acid storage battery is the oldest rechargeable battery in existence. It was invented in 1859 by French physician
Gaston Plante and still retains application todaY, more than 150
years later.
There are two reactions that take place during discharge of the lead-acid storage battery. In one step, sulfuric acid
decomposes to form sulfur trioxide and water:
H, SO,() – SO;(9) + H,O()
AH-+113. kJ
In another step, lead, lead(IV) oxide, and sulfur trioxide react to form lead(II) sulfate:
Pb(s) – PbO,(s) - 2 S0, (g) → 2 PbSO,(s)
AH= -775. J
Calculate the net change in enthalpy for the formation of one mole of lead(II) sulfate from lead, lead(IV) oxide, and
sulfuric acid from these reactions.
Round your answer to the nearest kJ.
Consider the combustion of a single molecule of CH4(g),forming H2O(l) as a product. (a) How much energy, in J,is produced during this reaction? (b) A typical X-ray lightsource has an energy of 8 keV (see inside back cover forconversion between eV and J). Is the energy released by thecombustion of a CH4 molecule larger or smaller than the energyof an X-ray from this source?
