Given the Freundlich isotherm equation x/m = 3P^(2/3), determine the mass of adsorbate if the pressure is halved and the mass of adsorbent remains constant at 10g.
💡 Hint: Start by substituting P/2 in the equation.
If the experimental values determine k = 2 and n = 0.5, what happens to adsorption if pressure increases?
💡 Hint: What could a fractional 'n' imply about the rate of increase?
