Consider the reaction Fe ₂ O ₃( ~s )+3 CO ( ~g ) 2 Fe ( l )+3 CQ ₂( ~g ) In accordance with Le-Chatlier's principle, which of the following will not disturbs the equilibrium?

Options

  1. AAddition of Fe ₂ O ₃
  2. BRemoval of CO
  3. CRemoval of CO ₂
  4. DAddition of CO

Correct answer

A. Addition of Fe ₂ O ₃

Step-by-step solution

The given reaction is Fe ₂ O ₃( s ) + 3 CO ( g ) 2 Fe ( l ) + 3 CO ₂( g ) . According to Le-Chatelier's principle, the equilibrium position of a reaction is affected by changes in the concentration of species that are in the gaseous or aqueous phase. Species in the solid or liquid phase have a constant activity (or concentration) and their addition or removal does not change the reaction quotient Q_c or the equilibrium constant K_c . In the given reaction, Fe ₂ O ₃ is in the solid state (s). Therefore, changing the
