1 kg of charcoal at 25 celsius adsorbs 0.62 moles of acetic acid from a 0.031 M aqueous solution and 2.48 moles from a 0.882 M soln.  Assuming that the Freundlich isotherm is applicable for this system, determine the Freundlich constants.  From these data, calculate how many moles of acetic acid from a 0.500 M solution will be adsorbed on the charcoal.

I have a formula but I don't know how to use it since the two unknowns are there.  This is the formula: y = kP^(1/n)  the n and k are the constants


Thank you very much.

Two simultaneous equations (one for each given solution) with two unknowns - just solve.

Thank you very much.

I have solved it.  Maybe I was tired I have'nt think of it.
