A mixture of 40% Argon and 60% Hydrogen by volume has been proposed for use as the working fluid in a closed Brayton cycle.

The mixture is compressed isentropically from 400oC at 0.4 MPa to a pressure of 1.2 MPa.

Find the final temperature of the mixture and the amount of work required, assuming ideal gas behavior is applicable.

Calculate the molar entropy change for argon and for hydrogen.

Why do the individual gases experience an entropy change during a process that is overall isentropic? [Hint: use properties of argon]
