The desorption of a single molecular layer of n -butane from a single crystal of aluminum oxide is found to be first order with a rate constant of 0.128>s at 150 K. a. What is the half-life of the desorption reaction? b. If the surface is initially completely covered with n -butane at 150 K, how long will it take for 25% of the molecules to desorb? For 50% to desorb? c. If the surface is initially completely covered, what fraction will remain covered after 10 s? After 20 s?
