How will a decrease in temperature, an increase in pressure and an increase in the concentration

How will a decrease in temperature, an increase in pressure and an increase in the concentration of CO2 in the systems affect the state of equilibrium: Fe2 O3 (t) + 3CO (g) = 2Fe (t) + 3CO2 (g) – Q CO2 (g) + C (t) = 2CO (g) – 72.6 kJ

According to Le Chatelier’s principle, if a reversible chemical reaction occurs in the system, the impact on the system will cause a shift in the chemical equilibrium towards compensating for this effect.

Fe2O3 (t) + 3CO (g) = 2Fe (t) + 3CO2 (g) – Q

decrease in temperature – a shift in the direction of the reverse reaction;

an increase in pressure – practically will not affect;

an increase in CO2 concentration is a shift towards the opposite reaction.

CO2 (g) + C (t) = 2CO (g) – 72.6 kJ

decrease in temperature – a shift in the direction of the reverse reaction;

an increase in pressure – a shift in the direction of a reverse reaction;

an increase in CO2 concentration is a shift towards a direct reaction.
