A chemistry graduate student is studying the rate of this reaction: 2H3PO4 (aq) → P₂O²(aq) + 3H₂O (aq) He fills a reaction vessel with H₂PO4 and measures its concentration as the reaction proceeds: time (seconds) 0 10. 20. 30. 40. [H₂PO4] 0.100M 0.0473 M 0.0224M 0.0106M 0.00500M Use this data to answer the following questions. Write the rate law for this reaction. 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. rate = k k = 0 ☐ x10 ロ・ロ X 2

Question
Answer or units should not include fractions/decimals (i.e. n=1.5 or M^-0.5)! Slope lines are to be used in calculating rate constant k, so including graph would be helpful.
O KINETICS AND EQUILIBRIUM Deducing a rate law from the change in concentration over time A chemistry graduate student is studying the rate of this reaction: 2H3PO4 (aq) → P₂O5 (aq) + 3H₂O (aq) He fills a reaction vessel with H₂PO4 and measures its concentration as the reaction proceeds: time (seconds) 0 10. 20. 30. 40. [H₂PO4] 0.100M 0.0473 M 0.0224M 0.0106M 0.00500M Use this data to answer the following questions. Write the rate law for this reaction. 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. rate = k - 0 k = ロ・ロ X 90 4
