Working with the decomposition of sucrose in acidic medium

Sucrose decomposes in acid solution, according to the first order rate law, to give Glucose and fructose. If the half life for the reaction is 3.33 hours at 25 degree celcius, what fraction of a sample of sucrose would remain after 9 hours ?

Solution Preview

Half life t_½ = 0.693/k

and k = 0.693/3.33 = 0.208 /hr

let the initial ...
