A solution that shows large negative deviation from Raoult's law
forms a maximum boiling azeotrope at a specific composition Nitric
acid and water is an example of this class of azeotrope This
azeotrope has an approximate composition of 68% nitric acid and 32%
water by mass
because of less composition of water T > 359K because dependency
of temperature is intentionally proportional to the solvent part in
the azeotropic mixture and in their solution water part is less
that's why T>359
