Question
1 mol of nitroethane is allowed to expand isothermally at T = 400 K from 1 m³ to 5 m³. If nitroethane obeys the Soave-Redlich-Kwong (SRK) equation of state, calculate the values of q, w, AU, AH, and AS. The SRK EOS is given by: RT a(Т) P = V -b (V+ eb)(V+ob) a(T) V -b RT V = 1 +b – P P (V+ eb)(V + ob) a(T,)R°T? a(T) = y Pe RT. b = 2. P.
