Homework Answers
- The correct answer is option (iii).
- The chemical potential value is inversely proportional to the value of standard molar Entropy.
- Therefore, higher the chemical potential, lower will be it's standard molar Entropy.
- The chemical potential of substance A is lower than that of substance B at temperatures above T1.
- Therefore,the standard molar Entropy of substance A is greater than that of substance B at temperatures above T1.

For all of the processes, you may assume the gases have the properties of pure air and are thermally and calorically perfect. For all processes except the exhaust nozzle, you may neglect kinetic and potential energy changes. Therefore, the static and stagnation properties are equal. 50 kg/s of air enters an adiabatic compressor at 1 atm and 300 K and compresses the air to 30 atm. The compressor has an adiabatic efficiency of 90%. The compressor adiabatic efficiency is W...
