In the following system, PCl ₅( ~g ) PCl ₃( ~g )+ Cl ₂( ~g ) at equilibrium, upon addition of xenon gas at constant T & p , the concentration of

Options

  1. APCl ₅ will increase
  2. BCl ₂ will decrease
  3. CPCl ₅, PCl ₃ & Cl ₂ remain constant
  4. DPCl ₃ will increase

Correct answer

B. Cl ₂ will decrease

Step-by-step solution

On addition of inert gas at constant P & 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 ] & [ Cl ₂ ] will increase.
