Question

What type of deviation in nitric acid + water. Accding to roults law

Answer 1

Raoult's law predicts/gives a relation between elevation in boiling point and the concentration of a solute in water.  Here the solute is Nitric acid  HNO3.

The boiling point of Nitric acid will be above 100 deg. C  depending on the concentration of HNO3 in it..  The boiling point deviates.
 
The partial vapour pressure of  water above its surface changes also.

Answer 2

Answer:

Negative deviation

Explanation:

Negative deviation is shown in nitric acid with water
