Some measurements of the initial rate of a certain reaction are given in the table below. [N] [H.] initial rate of reaction 0.794M 1.67M 0.518 M/s 0.376M 1.67M 0.245 M/s 0.794 M 5.07 M 4.77 M/s Use this information to write a rate law for this reaction, and calculate the value of the rate constant k. Round your value for the rate constant to 3 significant digits. Also be sure your answer has the correct unit symbol. rate = k 1. O. ロロ k= = 0 ] Х 5 ?
Consider this reaction: 2H,PO, (aq) + P,0, (aq) +3H,0 (aq) At a certain temperature it obeys this rate law. ate = (3.05 )[H,PO] Suppose a vessel contains H, PO at a concentration of 0.360M. Calculate how long it takes for the concentration of H,PO, to decrease to 0.022M. You may assume no other reaction is important. Round your answer to 2 significant digits. 0. х 5
A chemistry graduate student is studying the rate of this reaction: NH,OH(aq) → NH, (aq) +H20 (aq) - She fills a reaction vessel with NH,OH and measures its concentration as the reaction proceeds: time (milliseconds) [NH,OH] 0 0.100M 10. 0.0552M 20. 0.0381M 30. 0.0291M 40. 0.0235M Use this data to answer the following questions. Write the rate law for this reaction, rate = k Calculate the value of the rate constant k. k 0 = Х $ Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol.
