For the reaction: 3 Fe(s) + 4 H₂O(g) ⇌ Fe₃O₄(s) + 4 H₂(g) what is the effect on equilibrium of increasing temperature of an exothermic reaction?

Question

Quizplus · Accepted Answer

The reaction is exothermic, meaning heat is a product of the reaction. By Le Chatelier's principle, increasing the temperature will cause the reaction to shift to the side that will consume heat, which is the left side in this case. Therefore, the equilibrium will shift to the left, resulting in a decrease in the concentration of Fe₃O₄(s) and an increase in the concentration of H₂(g) and Fe(s).
