The following is a quote from an article in the August 18,1998, issue of The New York Times about the breakdown ofcellulose and starch: “A drop of 18 degrees Fahrenheit [from77 °F to 59 °F4 lowers the reaction rate six times; a 36-degreedrop [from 77 °F to 41°F] produces a fortyfold decrease inthe rate.” (a) Calculate activation energies for the breakdownprocess based on the two estimates of the effect of temperatureon rate.
