← ScienceWhich equilibrium shift occurs when inert gas boosts total pressure?
A)Equilibrium shifts toward fewer moles
B)Equilibrium position does not change✓
C)Reaction rate always significantly decreases
D)Reactions proceed toward reactant formation
💡 Explanation
Adding inert gas increases pressure, but it does not change the partial pressures of reactants/ products; therefore, the equilibrium position is unchanged, rather than shifting, because changes in partial pressures drive the equilibrium via Le Chatelier's principle.
