Solution

The correct option is D Assertion is incorrect but Reason is correct
For $P {C l}_{5} (g) ⇌ P {C l}_{3} (g) + {C l}_{2} (g)$ . If more ${C l}_{2}$ is added the equilibrium will shift in backward direction but, equilibrium constant will not be affected.
Addition of inert gas to the equilibrium mixture at constant volume, does not alter the equilibrium.
Assertion is incorrect but Reason is correct.
Note: In the above chemical reaction, $C l_{2}$ is one of the products. It is not an inert gas. When $C l_{2}$ is added, more and more $C l_{2}$ will react with $P C l_{3}$ to form $P C l_{5}$

Assertion – The non-fusible impurities present in iron ore are removed by $C a C O_{3}$ .

Reason: $C a C O_{3}$ which decomposes into $C a O$ and $C O_{2}$ . The $C a O$ formed reacts with $S i O_{2}$ to remove silica
