The hydrolysis of sucrose in excess acid solution follows first-order kinetics and results in D-glucose and D-fructose. Since, sucrose, D-glucose, and D-fructose are optically active compounds, the progress of the reaction can be monitored by measuring the angle of rotation of the polarized light in a polarimeter at different times. In a certain experiment, 1 L of 0.1 M sucrose solution is hydrolyzed and the angle of
Options
- AThe half-life of the reaction is 15 min .
- BThe rate constant (k) is 3.85 10⁻⁴ ~s ⁻¹ .
- CThe mass of sucrose hydrolysed in 60 min is 25.6 g .
- DThe rate of the reaction at 30 min is 1.925 10⁻⁵ Ms ⁻¹ .
Correct answer
D. The rate of the reaction at 30 min is 1.925 10⁻⁵ Ms ⁻¹ .
