← ScienceWhich outcome changes when adding inert gas to a closed-system equilibrium?
A)Partial pressures remain constant✓
B)Equilibrium shifts to reactants
C)Total pressure remains constant
D)Reaction rate increases sharply
💡 Explanation
Adding inert gas at constant volume does not change partial pressures because it does not react or displace any equilibrium components. Therefore, equilibrium is maintained rather than reactants/products being favored if components changed.
