Question

The following data were collected for the isomerization reaction:

Time (h) [C₃H₆] (M)
0.00 0.400
10.00 0.280
20.00 0.196
30.00 0.137
40.00 0.096


Determine the rate law.
A. Rate =k
B. Rate =k[C₃H₆]
C. Rate =k[C₃H₆]²

Answer 1

The rate law for the isomerization reaction is Rate = k[C₃H₆]. The correct answer is option: B. Rate =k[C₃H₆]

Step-by-step explanation:

The rate law for a reaction is determined by the experimentally observed relationship between the concentrations of reactants and the rate of the reaction. In this case, we have the data for the isomerization reaction:

Time (h) [C₃H₆] (M)

0.00 0.400

10.00 0.280

20.00 0.196

30.00 0.137

40.00 0.096

By observing the data, we can see that the reaction rate decreases as the concentration of C₃H₆ decreases. Therefore, the rate law for this reaction is Rate = k[C₃H₆] (option B).
