ENV 6015 Kinetics Problem Set 1. The inversion of sucrose proceeded as shown at 25 o C: The initial concentration of sucrose was 1.0022 moles/liter. Calculate the first order rate constant and the half-life of the reaction. Why does this reaction follow a first order law despite the fact water enters into the stoichiometric equation? How long would it take to invert 95% of a pound of sugar? C 12 H 22 O 12 + H 2 O C 6 H 12 O 6 Time, min. 0 30 60 90 130 180 Sucrose inverted-M/L 0 0.1001 0.1946 0.2770 0.3726 0.4626 2. Find the reaction order and rate constant for the decomposition of diazobenzenechloride at 50 o C if the initial diazobenzenechloride concentration is 10 grams liter. The reaction and nitrogen evolution are shown. C 6 H 5 N 2 Cl C 6 H 5 Cl + N 2 Time, min. 6 9 12 14 18 22 24 26 39 N 2 cm 3 evolved 19.3 26.0 32.6 36 41.3 45.0 46.5 48.4 50.4 58.3 3. A certain reaction is 10 percent complete in 15 minutes at 40 o C and in 3 minutes at 60 o C. Estimate its activation energy.
