Additional Problem 2

 The hydrolysis of sucrose, in which a sucrose molecule is broken down into a glucose molecule and a fructose molecule, is a part of the digestive process.  How strongly does the rate depend on the body temperature?  Calculate the rate constant for the hydrolysis of sucrose at 35^oC, given that k = 1.0 x 10^-3 M^-1 s^-1 at 37^oC (normal body temperature), and the activation energy of the reaction is 108 kJ mol^-1.  Ans.  7.6 x 10^-4 M^-1s^-1
