Assertion :Fuels with a higher octane rating are used in high performance gasoline engines while fuels with lower octane numbers are ideal for diesel engines Reason: Gasoline engines require higher compression ratios whereas diesel engines do not compress the fuel, but rather compress only air and then inject fuel into the air which was heated by compression

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

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
