Question

Consider the reaction:
NH4Cl (s) → NH3 (g) + HCl (g)
ArS 94.6 J K-¹mol-¹
=
ArH= 175.98 kJ/mol
a) Calculate the ArG for the reaction above at 30 °C.
b) As written, is this reaction endothermic or exothermic? At what temperature will this
reaction be spontaneous? Briefly justify your answer
c) Explain why the value of ArS is positive for this chemical reaction. List two circumstances
where A,S will be negative.
d) A gas mixture of total pressure 56 kPa consisting of 1 part NH3 to 1 part HCl was obtained
in the reaction above. Calculate the partial pressure of ammonia and hydrogen chloride gas
in the gas mixture.
e) How much work is done when a piston is compressed from 9.87 L to 2.56 L under constant
atmospheric pressure (1.013 × 105 Pa)?
f) Which intermolecular forces will be dominant between HCl molecules? Which has the
higher boiling point: HF or HCl? Briefly justify your answer
g) What intermolecular forces will be dominant between NH3 molecules? Briefly justify your
answer.
