Which of the following gases is adsorbed to a greater extent if the adsorbent remains the same under similar conditions of temperature and pressure?

In the $Langmuir$ adsorption model,the adsorption of a gas on a solid surface is:

Physical adsorption is inversely proportional to the

In the figure,a straight line is given for the Freundlich Adsorption isotherm equation $(y = mx + c)$,where the equation is $y = 0.3x + 0.7033$. The values of $\frac{1}{n}$ and $\log K$ are respectively:

For the adsorption of hydrogen on platinum,the activation energy is $30 \ kJ \ mol^{-1}$ and for the adsorption of hydrogen on nickel,the activation energy is $41.4 \ kJ \ mol^{-1}$. The logarithm of the ratio of the rates of chemisorption on equal areas of the metals at $300 \ K$ is $........$ (Nearest integer). Given: $\ln 10 = 2.3$,$R = 8.3 \ J \ K^{-1} \ mol^{-1}$.

Identify the gas which is readily adsorbed by activated charcoal.
