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

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

the answer is either b or c
