A chemical engineer is studying the rate of this reaction. 2N,0, (g) → 2N,O4g)+O2 (g) He fills a reaction vessel with N,O, and measures its concentration as the reaction proceeds. Here's a graph of his data: 2 1.5 - 0.5 0. 0.2 0.4 0.6 0.8 1.2 t (s) (x) [°o°n]
The rate of a reaction is monitored by measuring the number of moles of product that form per liter per second. The data obtained are listed in the table below. Using this data, mathematically determine the order with respect to each reactant, the overall order of the reaction, determine the rate constant, k, with units, and write the complete rate law.
