What is the effect of adding a catalyst on the equilibrium position of a redox reaction between iron(III) oxide and carbon monoxide, where iron is reduced and carbon is oxidized according to the following equation?Fe2O3 + 3CO ⇆ 2Fe + 3CO2 Calculate the equilibrium constant (Kp) of the reaction at 298 K in the presence and absence of a catalyst. Explain whether or not the presence of the catalyst will affect the position of equilibrium and justify the answer with relevant calculations.
