Subject :- ChemistryMuch of the sulfur used in the United States comes from the hydrogen sulfide contaminant that makes "sour" natural gas smell bad. Hydrogen sulfide is separated from the other components of natural gas mostly by taking advantage of its acid-base reaction with aqueous ethanolamine: HO(CH,),NH,(aq)+H,S(g) → HO(CH,),NH,(aq)+HS (aq) Suppose an engineer decides to study the rate of this reaction. She prepares four reaction vessels with 167.6 mL of ethanolamine solution and 20.9 g of hydrogen sulfide gas each. 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. vessel volume temperature A B C D 5.0 L 5.0 L 5.0 L 5.0 L 49, °C 48. °C 51. °C 50. °C X initial rate of…
