(15 points) For each of the following processes construct a process path consisting of sequential steps of the five types listed below. 1. Changes in P at constant T and state of aggregation 2. Changes in T at constant P and state of aggregation 3. Phase changes at constant T and P 4. Mixing of two liquids or dissolving of a gas or a solid in a liquid at constant T and P 5. Chemical reaction at constant T and P a) Steam at 500 bar (absolute) and 750C is cooled to a liquid at 50C and 1 bar. b) Acetic acid vapor at 200C and 3 atm is cooled and condensed to liquid at 20C and 3 atm. The enthalpy change for condensation of acetic acid at 118.2C and 1 atm is known. c) NH3 at 100C and 1 atm and O2 at 25C and 1 atm are mixed and react completely to form NO and H20 at 300C and 1 atm. The enthalpy change for the reaction occurring at 25C and 1 atm is known
