1.	Finely divided catalyst has greater surface area and has greater catalytic activity than the compact solid. If a total surface area of 6291456 `cm^(2)` is required for adsorption in a catalytic gaseous reaction, then how many splits should be made in a cube of exactly 1 cm in length to achieve required surface area? [Given : One split of a cube gives eight cubes of same size]A. `60`B. `80`C. `20`D. `22`
Answer» Correct Answer - C Total surface area of eight cubes `=8xx6xx(1/2xx1/2)` Apply the formula Surface area on a split of a cube `=8^(n)xx6xx(1/2)^(2n)` `6291456=8^(n)xx6xx(1/2)^(2n)`
