← ScienceWhich outcome occurs when adding inert gas at constant volume to a closed vessel containing reactants and products at equilibrium?
A)Equilibrium position remains unchanged✓
B)Equilibrium shifts towards more moles
C)Equilibrium shifts towards fewer moles
D)Increase in the total reaction rate
💡 Explanation
The equilibrium position remains unchanged because the addition of an inert gas at constant volume does not affect the partial pressures or concentrations of the reactants and products; therefore, the equilibrium constant is not affected, rather than impacting gas phase partial pressures.
