A flash distillation chamber operating at 101.3 kPa is separating an ethanol-water mixture. The feed mixture is 40 mol% ethanol and F = 100 kmol/h.

(1)What is the maximum vapor composition and what is the minimum liquid composition that can be obtained if V/F is allowed to vary?

(2) If V/F = 2/3, what are the liquid and vapor compositions?

(3) Repeat step 2, given that F is specified as 1000 kmol/h

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

idk what is it? is this a question that you know the answer or u dont
