Consider this reaction: 3Fe2O3(s) + CO(g) → 2Fe3O4(s) + CO2(g). Which of the following would increase the rate of the reaction?

murzikaleks [220]

<h3><u>Answer;</u></h3>

C. increasing the surface area of Fe2O3

<h3><u>Explanation;</u></h3>

The rate of reaction refers to the speed at which products are formed from reactants.
The rate of any chemical reaction depends on a number of factors which include, surface area, temperature, concentration of reactants among others.
<em><u>When solids and liquids react, increasing the surface area of the solid will increase the rate of reaction. Thus, decrease in the size of particles causes an increase in the total surface area of the solid and therefore increasing the rate of reaction.</u></em>
