A polystyrene plate is exposed to nitrogen gas to remove excess styrene by vaporization. The process occurs at 1 bar and T=17 C, where the P vapor of the styrene is 5.025 mm Hg and the nitrogen flows with an average speed of 30 m/s, parallel to the plate with a width of 0.1 m., 0.7 m long and 10 mm thick.

a. Calculate ky, kc, kG

b. Calculate the rate of the mass transfer process.
