Estimate the diffusivity of naphthalene in air at 323 k and 1.42 bar % by the wilke_lee equation. naphthalene: normal boiling point = 491.1, critical volume = 413 cm3/mol, mw = 128.2; air: sigma = 3.620 angstrom, epsilon/kapa = 97 k, mw =29.

What would be the original temperature of a gas that has a volume of 2.0 l and a pressure of 2.0 atm and an unknown temperature that the volume increased to 3.5 l in its pressure decreased to 1.0 atm if the final temperature is measured to be 11°c
