Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Assertion
The compressibility factor for hydrogen varies with pressure with positive slope at all pressures.
Reason
Even at low pressures, the repulsive forces dominate in hydrogen gas.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Note: Hydrogen gas shows positive deviation from ideal behavior and is less compressible. $Z > 1$ .

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
