The reaction of sucrose with water in an acidic solution is
C12H22O11 + H2O ---> C6H12O6 + C6H12O6
The reaction is first order with a rate constant of 6.17 × 10-4 s-1 at 35 °C, when [H+] = 0.10 M. Suppose that in an experiment the initial sucrose concentration was 0.40 M
A) What will the concentration be after exactly 4 hours (i.e., 4.00 h)?
B) How many minutes will it take for the concentration of sucrose to drop to 0.20 M ?

Kinetics
(1)Sucrose, C12H22O11, reacts slowly with water in the presence of an acid to form two other sugars, glucose and fructose, both of which have the same molecularformulas, but different structures.C12H22O11 + H2O ? C6H12O6 (glucose) + C6H12O6 (fructose)The reaction is first order and has a rate constant of 6.2 ? 10-5/s at 35?C when the H+ concentration is 0.10 M. Suppose that the initial concentration of sucrose inthe solution is 0.40 M. What will the sucrose concentration be after 2.0...
