RT + 1 1. A well-insulated vessel has two equal volume compartments separated by a membrane. On one side of the compartment contains one mole of a real gas at 500 K and 0.001 m. This gas can be described by the EOS, P = . The other side is evacuated. The membrane ruptures, and the gas fills the entire volume. (Total 50%) (a) Please derive an expression for (), using the thermodynamic web and the given equation of state. Use this expression to explain your results in part (d). (hint: cyclic relation) (10%) mol. ) Given cdeal = R, a = -1 [no) . please calculate entropy change in for Astys, Assur and Asuniy for the expansion. (10%) (9) Is this process reversible or irreversible? Justify your answer by considering the 2nd law of thermodynamics. (5%)
