2 N2O3(g) 4 NO2(g) + O2(g) Consider the decomposition of dinitrogen pentoxide shown above. In order to determine the rate of this reaction, we can measure the concentration of NaOs at various time intervals throughout the reaction. The data and graph of (N2Os) verses time are shown below. Time (0) o 200 400 600 800 1000 ol INOM 1.00 0.00 0.78 0.59 0.51 0.54 0.48 0.43 0.36 0.34 0.30 1200 1600 1.800 2000 Te (A) What is the average rate of consumption of N2Os in the first 200 seconds? NOTE: The sign is important! 0.0003 X M/sec (B) What is the average rate of consumption of N20s between 800 and 1200 seconds? 0.00014 M/sec (C) Which of the following is true as the reaction proceeds to longer times? The rate slows down because the concentration of reactants is larger. Rate slows down because the concentration of product is larger. Rate slows down because the concentration of reactant is smaller. Rate speeds up because the concentration of product is farger. Rate speeds up because the concentration of reactants is smaller. OOOOO
