Rate of Reaction

Q. 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) --> ZnSO4 (aq) + H2 (g) Suppose an engineer decides to study the rate of this reaction. She prepares four reaction vessels by adding 167.1 g of solid zinc and 80.0 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 vessel in decreasing order of initial rate of reaction. In other words select 1 next to the vessel in Wich the engineer can reasonably expect the initial rate of reaction to be the highest. And so one.
