Please help and be thorough! This question is a huge part of my final grade, actually. I just need to check my work! Thank you!

Q7) Which of the following are TRUE statements? (Tick all correct answers.) (a) An azeotrope obeys Raoult's law (b) Water and methylbenzene form an azeotropic mixture. (c) Azeotropes can be used to drive some equilibrium reactions to completion. O (d) An azeotrope always has a higher boiling point than both of its constituents. O (e) An azeotrope always has a lower boiling point than both of its constituents. (f) Azeotropes are a group of nitrogen containing compounds

Explanation / Answer

false(a) No it doesen't follow obey raoult's law and shows positive deviation from raoults law
PA >XAPA0
true(b)yes they have close boiling points and form azeotrope methylbenzene is nothing but toulene
true(c)yes Azeotropes can be used to shift chemical equilibria by removing products.
false(d)no. it can have positive deviation where boiling point is lower that both species for minimum boiling azeotrope or positive deviation.
false(e)no.  it can have negative deviation where boiling point is higher that both species for maximum boiling azeotrope or negative deviation.
false(f)no. as in previous statement methylbenzene water it can be any two mixture which boils at fixed temperature and not necessarily only nitrogen compounds
