The graph between $\log (\frac{x}{m})$ and $\log P$ is provided for the adsorption of $NH_3$ gas on a metal surface. Calculate the weight of $NH_3$ gas adsorbed by $50 \ gm$ of the metal surface at $2 \ atm$ pressure. (in $gm$)

Why does the white precipitate of silver halide become coloured in the presence of dye eosin?

The mass of gas adsorbed,$x$,per unit mass of adsorbent,$m$,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 $4 \text{ atm}$ is: (Given $\log 3 = 0.4771$)

Why are powdered substances more effective adsorbents than their crystalline forms?

Which of the following statements is incorrect for physical adsorption?

Four gases $A$,$B$,$C$,and $D$ have critical temperatures $5.3 \ K$,$33.2 \ K$,$126.0 \ K$,and $154.3 \ K$ respectively. For their adsorption on a fixed amount of charcoal,the correct order is:
