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 molecular formulas, 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 in the solution is 0.40 M. How many minutes will it take for the sucrose concentration to drop to 0.30 M?
