Calculate the activation energy for the acid hydrolysis of sucrose to give glucose and fructose using the data given below:
Temperature (oC) K (s-1)
24 4.8 x 10-3
28 7.8 x 10-3
32 13 x 10-3
36 20. x 10-3
40 32 x 10-3
b. Calculate the rate constant at 37oC.
c. Calculate the enthalpy change for the reaction, assuming that the solvation enthalpies of the sugars are negligible. Draw an energy profile for the overall process.
