Correct answer: C. 3.0

According to Freundlich adsorption isotherm:- x m = 1 n p+ k(y=m x+c) We have, k = 10=1 p = (0.3)=-0.523 =45^ so slope = 1 n = = 45^ =1 Thus, x m =(1)(-0.523)+1=0.4771 x m =3.0

The plot of x m (y-axis) and p(x -axis) is a straight line inclined at an angle of 45^ . When the intercept, K is 10 and pressure is 0.3 ~atm the amount of solute in grams adsorbed per gram of adsorbent ( 3=0.4771) ?
