Question

2 N205(g) rightarrow 4 NO2(g) + 02(g) Consider the decomposition of dinitrogen pentoxide shown above. In order to determine the rate of this reaction, we can measure the concentration of N2O5 at various time intervals throughout the reaction. The data and graph of [N2O5] verses time are shown below. What is the average rate of reaction for N2O5 in the first 200 seconds? NOTE: The sign is important! M/ sec What is the average rate of the reaction for N2O5 between 600 and 1600 seconds? M/ sec 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 speeds up because the concentration of product 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 reactants is smaller.
