Question

The mass of gas adsorbed, x , per unit mass of adsorbate, m , was measured at various pressures, p . A graph between log x m and log p gives a straight line with slope equal to 2 and the intercept equal to 0 . 4771 . The value of x m at a pressure of 4 atm is : (Given log 3 = 0 . 4771 )

Correct answer: 0

x m = k ( P ) 1 n log x m = log k + 1 n log P Slope = 1 n = 2 so n = 1 2 Intercept , log k &#160; = &#160; 0 . 477 So k &#160; = &#160; A n t i log &#160; ( 0 . 477 ) &#160; = &#160; 3 so x m = k ( P ) 1 n = 3 [ 4 ] 2 = 48
