Question:
In the following system,
$ PCl_5(g) \rightleftharpoons PCl_3(g) + Cl_2(g) $ at equilibrium, upon addition of xenon gas at constant T and p, the concentration of
In the following system,
$ PCl_5(g) \rightleftharpoons PCl_3(g) + Cl_2(g) $ at equilibrium, upon addition of xenon gas at constant T and p, the concentration of
Show Hint
Adding an inert gas at constant pressure and temperature increases the volume of the container. This causes the equilibrium to shift towards the side with more moles of gas.

- \( PCl_5 \) will increase
- \( Cl_2 \) will decrease
- \( PCl_5 \), \( PCl_3 \) and \( Cl_2 \) remain constant
- \( PCl_3 \) will increase
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
On addition of inert gas at constant P and T, reaction moves in the direction of greater no. of moles so it will shift in forward direction, so \( [PCl_5] \) decrease and \( [PCl_3] \) and \( [Cl_2] \) will increase.
