Iron ore is reduced to pure iron by smelting, during which the iron (iii) oxide in the ore reacts with carbon monoxide gas, like this: fe2o3s + 3cog → 2fes + 3co2g suppose an engineer decides to study the rate of this reaction. she prepares four reaction vessels with 158.8g of solid iron (iii) oxide and 33.9g of carbon monoxide 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. rate of reaction a 2.0l 1100.°c b 2.0l 1200.°c c 4.0l 1100.°c d 4.0l 1000.°c
