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:
NH,OH(aq) — NH, (aq)+H,O(aq)
He fills a reaction vessel with NH OH and measures its concentration as the reaction proceeds:
time
(minutes)
0
1.0
2.0
3.0
4.0
[NH,OH]
0.500M
0.103M
0.0576M
0.0399M
0.0305 M
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 =
