Make a reversible isobaric expansion to state b v44.8l., Ask an Expert

Academics

1 mol of an ideal gas starts in state A: (p=1atm, V=22.4L), make a reversible isobaric expansion to state B: (V=44.8L). make a reversible isochoric expansion to C: (p=0.5atm), and finally makes a reversible isothermal compression back to A. with Cvm= 3/2 R, find delta S for each step, and for the whole cycle.
\(undefined\)

Also, if one of the steps are irreversible, can the cycle be performed, give thesame answers (since delta S is a state function), and still follow the laws of thermodynamics? Explain your answer.
