What is the AH+ for this reaction?
16CO2(g) + 18H2O(g) → 2C3H180) + 2502(g)

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
