Question

A chemistry graduate student is studying the rate of this reaction: NH4OH(aq) ? NH3(aq) + H2O(aq) She fills a reaction vessel with NH4OH and measures its concentration as the reaction proceeds: time (minutes) | [NH4OH] 0 | 0.0500 M 1.0 | 0.0288 M 2.0 | 0.0166 M 3.0 | 0.00955 M 4.0 | 0.00550 M 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 = [?] Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol.

Step 1

We can do this by comparing the change in concentration over time. From t = 0 to t = 1 minute: Initial concentration: 0.0500 M Final concentration: 0.0288 M Change in concentration: 0.0500 - 0.0288 = 0.0212 M From t = 1 to t = 2 minutes: Initial concentration: Show more…
