Question
After the reaction below has reached equilibrium, using Le Chatlier's principle predict the shift in the reaction with the following perturbation(s): 3 Fe(s)+4 HO (g)Fej04 (s)+ 4 H2 (3)+ heat a.) Reaction will shift to the products side. b.) Reaction will shift to the reactants side. c.) No Effect Possible Answers: 5.) An increase in H20 (g) concentration: 6.) A decrease in gas pressure: 7.) Addition of Fes04 (s) from the reaction: ) A decrease in the temperature of the reaction 9.) Removal of H20 (g) from the reaction? 10.) Addition of H2 (g) from the reaction?Explanation / Answer
A/C to Le Chatlier's principle, if we change any property equilibrium, then the equilibrium will shift in a direction to cancel that change.
Hence, 5. A, towards product side to decrease the concentration of the water.
6. C, no effect since no of gas molecules on both sides are equal.
7. B, towards reactants side to decrease the amount Fe3O4
8. A, since decrease in temperature is exothermic. Here temperature is released.
9. B, towards reactants side to increase the amount water.
10. B, towards reactant side to decrease the amount H2.
