Question

Introduction of inert gas (at the same temperature) will affect the equilibrium if

• A. Volume is constant and $\Delta n_g\ne 0$
• B. Pressure is constant and $\Delta n_g\ne 0$
• C. Volume is constant and $\Delta n_g=0$
• D. Pressure is constant and $\Delta n_g=0$

Answer 1

Answer: (B)

Introduction of inert gas (at the same temperature) will affect the equilibrium if Pressure is constant and $\Delta n_g\ne 0$

For constant volume, reaction quotient (Q) will remain constant.

For constant pressure, reaction quotient (Q) will remain constant when $\Delta n_g=0$ .
