Question
A mixture of benzene (1) and ethanol (2) at 45 ° C, a combination of vapor and liquid phases It is in equilibrium at 0.4093 bar pressure, and the ethanol in the liquid and vapor phases their compositions (as mole fraction) have values of 0.5284 and 0.4101, respectively. It is accepted that the vapor phase under conditions behaves like an ideal gas. The following of the vapor phase Calculate the properties: a) Gibbs free energy, G (J*mole^-1) b) Entropy, S (J*mole^-1*K^-1) c) Enthalpy, H (J*mole^-1) d) The fugacity values of benzene and ethanol in solution (kPa) *Take the enthalpy and the entropy values as zero for benzene and ethanol in ideal gas state, saturated vapor form at 273 K ig E= A +BT + CT². R *The saturated vapor pressure values can be calculated in accordance with the Antoine equation.
