The experiment shown below is used to estimate mass transfer coefficients. In the present experiment, two portions of the inside of the tube are coated with naphthalene, a volatile solid. The tube is maintained at 100°C and 1.0 atm total system pressure. At 100°C, the sublimation vapor pressure of solid naphthalene is 1.0 mmHg.

A sample of solid naphthalene is introduced into an evacuated flask and allowed to sublime. Use the data below to calculate the equilibrium vapor pressure of naphthalene (C10H8) in the flask at 35C. (1 atm =760 mmHg)[ R = 8.314 J/(mol.K)] C10H8(s) ⇌ C10H8(g) the answer is (0.12 mmHg) can you please explain how to get there? thank you!

Examples of this are temperature, pressure, density, concentration, and viscosity. 2.1. "Time" is not a "degree of freedom" when using the phase rule because time is not a property belonging to the substance being analyzed. 2.2. DF @ eutectic = 2 (biphenyl and naphthalene) – 3 (solid [naphthalene & biphenyl]) + 2 DF @ eutectic = 1 3.
