A plot of log x/m versus log p for the adsorption of a gas on a solid gives a straight line with slope equal to:

  • -log k

  • n

  • 1/n

  •  log k

Solution

C.

1/n

The empirical relation x/m = kp1/n put forward by Freundlich is known as Freundlich adsorption isotherm. Taking logarithm
log space straight x over straight m space equals space log space straight k space plus 1 over straight n space log space straight p
If the following curve is plotted
