← ScienceWhich outcome shifts a gaseous reaction's equilibrium when total pressure increases via argon addition?
A)Equilibrium shifts towards fewer gas molecules
B)Equilibrium remains unchanged✓
C)Reaction rate dramatically increases
D)Partial pressures directly increase
💡 Explanation
Inert gas addition doesn't influence the equilibrium because the partial pressures of reactants/products stay the same. The mechanism is dilution. Therefore, total pressure shifts do not influence the equilibrium of gases; rather than affecting partial pressures, it just decreases the mole fraction.
