A chemistry graduate student is studying the rate of this reaction: 2N,0(g) 2N,04 (8) +02 (8) He fills a reaction vessel with N2O3 and measures its concentration as the reaction proceeds: time (seconds) [N205] 0 0.0600M 0.10 0.0306M 0.20 0.0157 M 0.30 0.00799 M 0.40 0.00408 M Use this data to answer the following questions. Use this data to answer the following questions. Write the rate law for this reaction. rate = k X10 Calculate the value of the rate constant k. Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. 5
