4.25 Sucrose decomposes in acid solution into glucose and fructose according to the first order rate law, with hours. What fraction of sample of sucrose remains after 8 hours ?
For first order reaction,
given that half life = 3 hrs ()
Therefore k = 0.693/half-life
= 0.231 per hour
= antilog (0.8024)
Therefore fraction of sample of sucrose remains after 8 hrs is 0.157
