$3 \, g$ of activated charcoal was added to $50 \, mL$ of acetic acid solution $(0.06 \, N)$ in a flask. After an hour,it was filtered and the strength of the filtrate was found to be $0.042 \, N$. The amount of acetic acid adsorbed (per gram of charcoal) is: .............. $mg$

What type of phenomenon is adsorption? What type of reaction is adsorption?

Which of the following forces is responsible for physisorption?

Adsorption of gases on a solid surface is generally exothermic because

$A$ solid acts as an adsorbent because it has

For Freundlich adsorption isotherm,a plot of $\log (x / m)$ ($y$-axis) and $\log p$ ($x$-axis) gives a straight line. The intercept and slope for the line is $0.4771$ and $2,$ respectively. The mass of gas,adsorbed per gram of adsorbent if the initial pressure is $0.04 \ atm,$ is $........\times 10^{-4} \ g$.
$(\log 3 = 0.4771)$
