The equilibrium reaction P C l 5 ( s ) ⇌ P C l 3 ( s ) + C l 2 ( g ) is carried in a closed vessel. What is the effect on equilibrium concentration of C l 2 ( g ) by adding P C l 5 at constant temperature?

Options

  1. AUnaffected
  2. BIncreases
  3. CDecreases
  4. DCannot be described without the value of K p

Correct answer

B. Increases

Step-by-step solution

On adding more P C l 5 , equilibrium shifts forward, hence concentration of C l 2 ( g ) increases.
