i) Iron metal is obtained

ii) Fe2O3 + 3CO → 2Fe + 3CO2

iii) CO is the reducing agent

Explanation:

i) When carbon monoxide is passed over iron III oxide, iron metal is obtained

ii) The equation of the reaction is;

Fe2O3 + 3CO → 2Fe + 3CO2

iii) The reaction is a redox reaction. CO acts as the reducing agent while Fe2O3 acts as the oxidizing agent. We know that CO is the reducing agent because its oxidation number increased from left to right. Recall that the oxidation number of the reducing agent increases from left to right in a redox reaction
