The heat of reaction for the process described in (a) can be determined by applying Hess's law. The heats of reaction shown in the table below can be obtained experimentally or looked up
in tables of enthalpy data. Which two of these heats of reaction would be the easiest and safest to measure in the laboratory, and which two are better obtained through reference sources? Why?
Hint: Consider whether a reaction takes place in aqueous solution or instead involves noxious
gases.
Reaction
NH3(g) --> NH3(aq)
NH3(aq)+ HCI(aq)โ> NH4+(aq)+Cl-(aq)
HCI(g)โ>HCI(aq)
NH4Cl(s)โ>NH4+(aq)+Cl-(aq)
Heat of reaction
AH=-36.64 kJ/mol
AH=-51.6 kJ/mol
AH=-75.14 kJ/mol
AH=+14.8 kJ/mol

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
