This problem is describing a gas mixture whose mole fraction of hexane in nitrogen is 0.58 and which is being fed to a condenser at 75 °C and 3.0 atm, obtaining a product at 3.0 atm and 20 °C, so that the removed heat from the system is required.
In this case, it is recommended to write the enthalpy for each substance as follows:
Whereas the specific heat of liquid and gaseous n-hexane are about 200 J/(mol*K) and 160 J/(mol*K) respectively, its condensation enthalpy is 31.5 kJ/mol, boiling point is 69 °C and the specific heat of gaseous nitrogen is about 29.1 J/(mol*K) according to the NIST data tables and 
and 
are the mole fractions in the gaseous mixture. Next, we proceed to the calculation of both heat terms as shown below:
It is seen that the heat released by the nitrogen is neglectable in comparison to n-hexanes, however, a rigorous calculation is being presented. Then, we add the previously calculated enthalpies to compute the amount of heat that is removed by the condenser:
Finally we convert this result to kJ:

The Nuremberg War Crimes trials established the international legal precedent that individuals who violate human rights can be held responsible for their actions. The correct option in regards to all the options given in the question is option "2".
The Nuremberg trials were held
against the Germans by the Allied forces against the war crimes done by the
Germans during World War II. Many of the allied countries were in favor of
killing the war criminals before any trial, but ultimately the trial was held
and the criminals were either hanged to death of were killed by the firing
squad.
