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:
250, (g) 250, (g)+0₂ (g)
He fills a reaction vessel with SO3 and measures its concentration as the reaction proceeds:
[503]
time

0.00909 M
40. 0.00611 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 =
