The evaporation of a 120 nm film of n -pentane from a single crystal of aluminum oxide
Chapter 13, Problem 96(choose chapter or problem)
The evaporation of a 120 nm film of n -pentane from a single crystal of aluminum oxide is zero order with a rate constant of 1.92 * 1013 molecules>cm2 # s at 120 K. a. If the initial surface coverage is 8.9 * 1016 molecules>cm2 , how long will it take for one-half of the fi lm to evaporate? b. What fraction of the fi lm is left after 10 s? Assume the same initial coverage as in part a.
