This overall second-order reaction was performed in methanol solvent with equimolar amounts of DMB and acrolein (C. R. Clontz, Jr., M.S. Thesis, Univ. of Virginia, 1997.) Use the data shown below to evaluate the rate constant at each temperature.
For the aluminum fins in Problem 1. determine the temperature of a point on the fin 45 mm from the base. Also compute the fraction of the total heat that is lost through this section of the fin....
