A mixture of two high-boiling organic acids is to be separated from nonvolatile impurities by steam distillation at 373 K under a total pressure of 20 kPa. The organic acid mixture contains
30 mol% low boiling acid and 70 mol% high boiling acid and at 373 K the vapour pressures of
the two acids are 2.7 kPa and 1.1 kPa, respectively. The acid mixture obeys Raoult's law and
are immiscible with water. Determine the kilograms of steam required per kmol of acid
recovered

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
