Question

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: Fe2O3(s)+3CO(g) → 2Fe (s)+3CO2() Suppose an engineer decides to study the rate of this reaction. She prepares four reaction vessels with 93.4 g of solid iron (III) oxide and 29.8 g of carbon monoxide gas each. The volume and temperature of each vessel is shown in the table below. 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. initial rate of reaction vessel volume temperature A 5.0 L 1000 °C B 2.0L 1100.C C 3.0 L 1100 °C ? D 3.0L 1000. "C 1 x I ?

Answer 1

vessel	volume	temperature	initial rate of reaction
A	5.0 L	1000. oC	4
B	2.0 L	1100. oC	1
C	3.0 L	1100. oC	2
D	3.0 L	1000. oC	3

Explanation

initial rate of reaction is directly proportional to temperature and inversely proportional to volume.
