Benzene is contained in an open beaker of height (6 mathrm{~cm}) and filled to within (0.5 mathrm{~cm})
Question:
Benzene is contained in an open beaker of height \(6 \mathrm{~cm}\) and filled to within \(0.5 \mathrm{~cm}\) of the top. The temperature is \(298 \mathrm{~K}\) and the total pressure is \(1 \mathrm{~atm}\). The vapor pressure of benzene is \(0.131 \mathrm{~atm}\) under these conditions, and the diffusion coefficient is \(9.05 \times 10^{-6} \mathrm{~m}^{2} / \mathrm{s}\).
Find the rate of evaporation based on
(a) the low-flux model,
(b) exact solutions, and
(c) the low-flux model corrected for the drift flux.
