Question

Give the mathematical expression for Freundlich adsorption isotherm​

Answer 1

Answer:

Freundlich isotherm explains the behaviour of adsorption accurately. In the equation – x/m = k.P1/n (n > 1), 'k' and 'n' are constants that depend on the nature of the adsorbent and the gas at a particular temperature.

Answer 2

Answer:

The freundich adscription isotherm is mathematically expressed as

m

x

=Kp

1/n

It is also written as

log

m

x

=logK+

n

1

logp

or,

m

x

=Kc

1/n

It is also written as

log

m

x

=logK+

n

1

logc

where,

x = mass of adsorbate

m = mass of adsorbent

p = Equlibrium pressure of adsorbate

c = Equilibrium concentration of adsorbate in solution
