An ideal gas with Cp = 2.5R at 298 K and 5.00 bar is adiabatically throttled to 1.00 bar. (Note this is a continuation of the previous problem.)

What is the change in entropy of the system, in J/mol/K? Please give your answer to 3 SF.

Answer #1

Since Throttling process is adiabatic.

So no heat exchange with surroundings.

delta Q=0

delta S = delta Q/T

delta S=0

Let verify it by calculation.
