NEETChemistryIonic Equilibrium
A sample of pure ( PCI 5 ) was introduced into an evacuated vessel at (473 ~K ). After equilibrium was attained, the concentration of ( PCI 5 ) was found to be (0.5 10⁻¹ ~mol ~L ⁻¹ ). If the value of (K_c ) is (8.3 10⁻³ ), what are the concentrations of ( PCl 3 ) and ( Cl 2 ) at equilibrium? (P C l 5(g) P C l 3(g)+C l 2(g) )
Options
- A([P C l 3]=0.035 ~mol ~L ⁻¹,[C l 2]=0.035 ~mol ~L ⁻¹ )
- B([P C l 3]=0.015 ~mol ~L ⁻¹,[C l 2]=0.015 ~mol ~L ⁻¹ )
- C([P C l 3]=0.030 ~mol ~L ⁻¹,[C l 2]=0.030 ~mol ~L ⁻¹ )
- D([P C l 3]=0.040 ~mol ~L ⁻¹,[C l 2]=0.040 ~mol ~L ⁻¹ )
Correct answer
A. ([P C l 3]=0.035 ~mol ~L ⁻¹,[C l 2]=0.035 ~mol ~L ⁻¹ )
Step-by-step solution
Correct Option is : (A) ([P C l 3]=0.035 ~mol ~L ⁻¹,[C l 2]=0.035 ~mol ~L ⁻¹ )
