We discussed the Young-Laplace equation: Poured = Post + (1/r + 1/r)* y to describe the vapor pressure

at a curved surface. Increased curvature will correspond to a decreased radius. In the equation, y is the surface energy.

Use graphing software to make a plot showing the change in equilibrium vapor

pressure with radius of curvature for a spherical material from 1 nm to 1 mm at 770 C which has a Pinat value of 3.4 x 10 Torr. The molar volume of the material is 1.6 x 105 m and the surface energy is 0.56 J m2. To do this correctly, the units on the given quantities will have to be consistent.
