The hydrolysis of sucrose (C12H22O11) produces fructose and glucose (each C6H12O6). Two mechanisms are proposed:

Question

I) Step 1: C12H22O11 --> C6H12O6 + C6H10O5 (slow)
Step 2: C6H10O5 + H2O--> C6H12O6 (fast)

II) C12H22O11 + H2O--> C6H12O6 + C6H12O6

Would these mechanisms be distinguishable in a dilute solution using kinetic data?
