k is Boltzmann's constant, R is the gas constant. N is the number
of H2 molecules, n is their concentration. V are the volumes.
As the process is isothermal you just divide by T to get the entropy
Caveats: Industrially one may not have the time to ensure a reversible
process - this will increase entropy generation, but not energy
requirements. However, the lack of a large cold reservoir in turn will
probably require some cooling increasing energy requirements, and entropy
generation for the heat engine which does the cooling.

Does any member of this group have articles, information, views or comments
about DINOSAURS and their relation to Fossil Energy Civilization ?
Those ole Sauriens can hardly be symbols of 'awareness', but how come they
got to be cult image/icons in the space of maybe 15 years? Is this a Dark
Bond between Fossil Energy Citizenry and the geological age that made our
wonderful world possible? Or good marketing by Spielberg & Co?
Please contact me if you have ideas
- Would there really be so great a philosophical or symbolic difference
between using crude and refined oil? If so, what would it be?
