Question

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?

Answer 1

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
