(a)
Interpretation : A balanced chemical equation for the combustion of octane needs to be determined.
Concept Introduction : In a balanced
The enthalpy of reaction can be defined as the energy change during chemical reaction. The value is positive for an endothermic and negative for an exothermic reaction. If the energy is released in a reaction, the reaction is exothermic and if it is evolved, the reaction is endothermic.
(b)
Interpretation : The amount of energy produced in kJ from octane in one tank.
Concept Introduction : In the chemical reaction, reactant molecules react to form products. The mass of a substance is related to its number of moles and molar mass as follows:
Here, m is mass and M is molar mass.
Also, 1 mole of a substance contain
The enthalpy of reaction can be defined as the energy change during chemical reaction.
(c)
Interpretation : The number of molecules of octane present in 1 tank of fuel needs to be calculated.
Concept Introduction : In the chemical reaction, reactant molecules react to form products. The mass of a substance is related to its number of moles and molar mass as follows:
Here, m is mass and M is molar mass.
Also, 1 mole of a substance contain
The enthalpy of reaction can be defined as the energy change during chemical reaction.
(d)
Interpretation : The mass of carbon dioxide produced from the combustion of fuel if the car covers 24500 miles in a year.
Concept Introduction : From the number of moles, mass can be calculated as follows:
Here, n is number of moles and M is molar mass.
From the distance travelled, the volume of fuel consumed can be calculated from its mileage.

Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference.
