Question

For the following reaction 3 experiments have been run and the data collected is in the following table @ 25 degrees Celsius.

                                   NH4NO2(aq) ---> N2(g) + 2 H2O(l)

Experiment  [NH4NO2], M Rate, M/s 
1 1.22 x 10-2 1.12 x 10-4
2 2.61 x 10-3 5.12 x 10-6
3 3.54 x 10-3 9.42 x 10-6

a) How long (in seconds) will it take for a 30% NH4NO2 solution to become a 19% NH4NO2 solution @25 degrees Celsius? (Hint: Use mass ratios and assume ~1g/ml for density of solutions to get you started)

b) It has been determined that the rate constant is 1.3450 M-1s-1 at 65 degrees Celsius. Calculate the activation energy for the decomposition of NH4NO2. [Hint: ln k1/k2=?a/?(1/?2―1/? 1)]

c) What is the half-life of a 45% solution of NH4NO2 @ 25 degrees Celsius?
