Question:
1. Dinitrogen pentoxide (N2O5) decomposes to NO2 and O2 atrelatively low temperatures in the reaction 2N2O5(soln) →4NO2(soln) + O2(g) This reaction is carried out in a CCl4 solutionat 45° C. The concentrations of N2O5 as a function of time arelisted in the table. Plot a graph of the concentration versus t, ln(natural log) concentration versus t, and 1/concentration versus t.Graphically, determine the order of the reaction, write the ratelaw and calculate the value of the rate constant. What is thehalf-life for this reaction (at the initial concentration)? Howlong will take for 90% of the initial concentration of N2O5 to beconverted to products?

2. 1, 3-Butadiene (CH2=CH-CH=CH2) is a volatile and reactiveorganic molecule used in the production of rubber. Above roomtemperature it reacts slowly to form products. Concentrations of1,3-butadiene (C4H6) as a function of time at 326°C are listed inthe table below. Graph the data as concentration versus t, ln(natural log) concentration versus t, and 1/concentration versus t.Graphically, determine the order of the reaction, write the ratelaw and calculate the value of the rate constant. What is thehalf-life for this reaction (at the initial concentration)? Howlong will take for 80% of the initial concentration of1,3-Butadiene to be converted to products?
