This problems deals with condensation of a
given vapor mixture. You need to have knowledge of mass balances, equilibirum
ratios and interpretating DePriester Charts.
You need to know when to use fugacities, equilibirum
ratios, raoult's law for real gases and activity co-efficients to solve
this problem about solubility.
This probem deals with heats
of reaction and is a very elementary problem in which you use the heat
of combustion to calculate the heat of formation.
Problem #4 is gives you a certain
process and asks you to calculate the energy changes and work effects
in constant pressure and constant volume situations.
Here, you are asked to compute
the entropy change associated with the mixing of 2 gases.
Tests your understanding of reversibility,
irreversibility and impossibility as pertaining to heat engines.
