Right Applying the principle of Le Chatelier When the concentration of one of the (gaseous) products falls, the equilibrium moves to the right (to the products). Change in the amount of #Fe_3O_4# will not affect the equilibrium as it is in the solid state. (Only change in concentration of gaseous or aqueous reactants affects the equilibrium.) Dry ice (solid carbon dioxide) sublimate readily to produce gaseous #CO_2#, increasing the concentration of products. (Also, the reaction is endothermic. https://tutor.hix.ai) Changes in volume have no effect on the equilibrium because there are equal numbers of gas molecules on both sides of the reaction (though they do speed up reactions in both directions). Adding #CO (g)# will increase the concentration of the reactants.

undefined 1. Increase in CO concentration: Shifts right
2. Increase in CO2 concentration: Shifts left
3. Increase in FeO concentration: Shifts left
4. Increase in Fe3O4 concentration: Shifts right
5. Increase in temperature: Shifts endothermic direction
6. Decrease in temperature: Shifts exothermic direction
7. Increase in pressure: Shifts to the side with fewer moles
8. Decrease in pressure: Shifts to the side with more moles
