Shown below are adsorption isotherms for a gas '$X$' at temperatures $T_1$,$T_2$,and $T_3$. Here,$p$ and $\frac{x}{m}$ represent pressure and the extent of adsorption,respectively. The correct order of temperatures for the given adsorption is:

$A$ gas undergoes physical adsorption on a surface and follows the given Freundlich adsorption isotherm equation $\frac{x}{m} = k p^{0.5}$. Adsorption of the gas increases with

Adsorption is always

During the adsorption of a gas on a solid at low temperature,which of the following thermodynamic conditions is correct?

The plot of $\log \frac{x}{m}$ ($y$-axis) and $\log p$ ($x$-axis) is a straight line inclined at an angle of $45^{\circ}$. When the intercept is $\log K = 0.3010$ (where $K = 2$) and pressure is $0.3 \ atm$,calculate the amount of solute in grams adsorbed per gram of adsorbent $\frac{x}{m}$ (given $\log 3 = 0.4771$ and $\log 0.3 = -0.5229$)?

According to the Langmuir adsorption isotherm,at high pressure,the amount of gas adsorbed is .......
