Question 1

Use the DfH° and DrH° information provided to calculate DfH° for IF:

DfH° (kJ mol-1) IF7(g) + I2(g) → IF5(g) + 2IF(g)DrH° = -89 kJ
IF7(g)-941
IF5(g)-840

◦ 101 kJ mol-1
◦ -190. kJ mol-1
◦ -146 kJ mol-1
◦ -95 kJ mol-1
◦ 24 kJ mol-1

Question 2

Use the DfH° and DrH° information provided to calculate DfH° for SO3(g):

DfH° (kJ mol-1)2SO2(g) + O2(g) → 2SO3(g)DrH° = -198 kJ
SO2(g)-297

◦ -495 kJ mol-1
◦ -578 kJ mol-1
◦ -248 kJ mol-1
◦ -396 kJ mol-1
◦ -792 kJ mol-1
