Question

question 14 of 32 the reaction below is at equilibrium. what would happen if more carbon were added? c(s) + o₂(g) ⇌ co₂(g) a. the equilibrium position would shift to produce more products. b. the equilibrium position would remain the same. c. the equilibrium position would shift to produce more reactants. d. the equilibrium position would shift to produce more oxygen.

Explanation:

To determine the effect of adding more carbon (a solid) to the equilibrium reaction \( \text{C}(s) + \text{O}_2(g)
ightleftharpoons \text{CO}_2(g) \), we use Le Chatelier's principle. Le Chatelier's principle states that a change in concentration, pressure, or temperature of a system at equilibrium will cause the system to shift in a direction that counteracts the change. However, the concentration of a solid (like carbon) is considered constant and does not appear in the equilibrium expression. Therefore, adding more solid carbon does not change the effective concentration of reactants or products that influence the equilibrium position. Thus, the equilibrium position remains unchanged.

Answer:

B. The equilibrium position would remain the same.
