If the gas-solid equilibrium amounts to a monolayer capacity of 150cc(STP)/g of N2 (16.2e -20 m^2/ molecule), the surface area of 1g of the solid adsorbent exceeds 850 m^2. True or False?
true :
explanation:
generally surface area char coal
surface area of char coal = 1g = 1/12 mol
= 1 x 6.023 x 10^23 / 12 molecules
= 5.019 x 10^22 molecules
so capacity = (16.2e -20 m^2/ molecule ) x 5.019 x 10^22 molecules
= 8131 m^2
it is more value than 850 m^2 . so the above statement is true
