In The Laboratory Hydrogen Gas Of Good Purity Can Most Easily Be Obtained By The Reaction Of A Strong Acid Like Sulfur 1 (68.58 KiB) Viewed 14 times

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) + H₂SO4 (aq) - ZnSO₂(aq) + H₂(g) Suppose an engineer decides to study the rate of this reaction. He prepares four reaction vessels by adding 131.1 g of solid zinc and 74. 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. da P vessel volume temperature initial rate of reaction 4 A 5.0 L 2.0 °C ? 5.0 L -2,0 °C ? v 5.0 L 0 °C |?
