Q1)
part A:
Consider the decomposition of NOCl: 2NOCl(g) → 2NO(g) + Cl2(g)
During the decomposition, the concentration of cyclopropane is measured. By graphing [NOCl] vs. time, ln[NOCl] vs. time and 1/[NOCl] vs. time, the plot of 1/[NOCl] vs. time gives a straight line with a slope of 9.98 x 10-2 at 129oC.
(a) What is the reaction order for the decomposition of NOCl.
(b) Calculate the rate constant of the reaction.
(c) If the initial concentration of NOCl(g) is 0.200 M, calculate half-life of the decomposition reaction.
part B:
The reaction of sucrose with water has a rate constant of 6.21 x 10-5 s-1 at 35oC. Sucrose(aq) + H2O(l) → glucose(aq) + fructose(aq)
(a) What is the reaction order for the reaction? (b) Calculate the half-life of the reaction at 35oC.
(c) How long would it take for the concentration of sucrose to drop to one-quarter of its initial value at 35oC?
(d) At a particular temperature, the half-life of the decomposition of sucrose is 849 s. Determine the rate constant at the particular temperature.
