Question
Transcribed Image Text:In the laboratory, hydrogen gas of good purity can most easily be obtained by the reaction of a strong acid, like sulfuric acid, on a reactive metal, such as zinc:
Zn(s)+H,SO,(aq)
ZnSO,(aq)+H, (g)
Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels by adding 160.9 g of solid zinc and 83. mL of 5.0 M sulfuric
acid solution to each, and then filling the remainder of the vessel with distilled water. The volume and temperature of each vessel is shown in the table below.
Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably
expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on.

Expert Solution
Step 1
Given Reaction:-
Zn(s) + H₂SO4 (aq) → ZnSO4 (aq) +H₂(g)
Mass of zinc = 160.9 g
Volume of sulphuric acid = 83mL or 0.083L
Molarity of sulphuric acid = 5.0 M
Arrange the reaction vessels in decreasing order of initial rate of reaction. In other words, select a "1" next to the vessel in which the engineer can reasonably
expect the initial rate of reaction to be highest, a "2" next to the vessel in which the initial rate of reaction would be next highest, and so on.
