Question 1

Choose the thermochemical equation that illustrates DfH° for Li2SO4.
◦ 2Li+(aq) + SO42-(aq) → Li2SO4(aq)
◦ 8Li2SO4(s) → 16Li(s) + S8(s, rhombic) + 16O2(g)
◦ Li2SO4(aq) → 2Li+(aq) + SO42-(aq)
◦ 16Li(s) + S8(s, rhombic) + 16O2(g) → 8Li2SO4(s)
◦ 2Li(s) + 1/8 S8(s, rhombic) + 2O2(g) → Li2SO4(s)

Question 2

Use the DfH° information provided to calculate DrH° for the following:

DfH° (kJ mol-1) SO2Cl2 (g) + 2H2O(l)→ 2HCl(g) + H2SO4(l)DrH° = ?
SO2Cl2(g)-364
H2O(l)-286
HCl(g)92
H2SO4(l)-814

◦ +800. kJ mol-1
◦ +161 kJ mol-1
◦ -256 kJ mol-1
◦ -62 kJ mol-1
◦ -422 kJ mol-1
