Calculate the standard enthalpy of formation of the M20(s) metal oxide (AH in
kJ/mol) using the following data:
Bond dissociation enthalpy of O2(g) = +498 kJ/mol
First electron affinity of O = -141 kJ/mol
Second electron affinity of O = +744 kJ/mol
Enthalpy of sublimation of M = + 124 kJ/mol
First ionization energy of M = + 372 kJ/mol
Lattice enthalpy of M20(s) = -2115 kJ/mol
Refer to the textbook for definitions of ionization energy and electron affinity. Do
not use scientific notation for your answer. Do not enter units.
Your Answer:
Answer
Ammonia is an important chemical used in the
production of fertilizer. Industrial production of
ammonia from atmospheric nitrogen is difficult
because of the energy required to cleave the
N-N triple bond. Consider the balanced reaction
of ammonia: N2(g) + 3H2(g) → 2 NH3 (9).
This reaction has a value of K = 4.3 x 10-2 at 25
°C.
Part A
Estimate the AH for this reaction using bond energies.

The amount of iodine produced by the redox reaction is determined by titration with sodium thiosulfate, Na2S2O3; I2 is reduced to I-.
