The reaction, Sucrose→Fructose+Glucose, takes place at a certain temperature while the volume of the solution is maintained at 1 L. At t = 0, the initial rotation of the mixture is 34∘. After 30 minutes the total rotation is 19∘and after a very long time, the total rotation is −11∘. Find the time when solution was optically inactive.

Answer» The reaction, $S u c r o s e \to F r u c t o s e + G l u c o s e$ , takes place at a certain temperature while the volume of the solution is maintained at 1 L. At t = 0, the initial rotation of the mixture is $34^{\circ}$ . After 30 minutes the total rotation is $19^{\circ}$ and after a very long time, the total rotation is $- 11^{\circ}$ . Find the time when solution was optically inactive.
