Question

Sucrose decomposes in acid solution into glucose and fructose according to first order

kinetics with half-life of 3 hours. Calculate the time required for ninety percent

decomposition​

Answer 1

Explanation:

Sucrose decomposes in acid solution into glucose and fructose according to the first order rate law, with t1/2 = 3.00 hours. What fraction of sample of sucrose remains after 8 hours? Hence, the fraction of sample of sucrose that remains after 8 hours is 0.158.
