In an adsorption experiment, a graph between $\log \left(\mathrm{x}/\mathrm{m}\right)$ vs $\log \mathrm{P}$ was fotund to be linear with a slope of ${45}^o$. The intercept on the $\log \left(\mathrm{x}/\mathrm{m}\right)$ axis was found to be $0.3$. The amount of the gas adsorbed per gram of charcoal under a pressure of $1 \mathrm{atm}$ is

The following graph is obtained for physisorption of a gas as a function of pressure at different temperatures.

The correct order of the temperatures is:

Which of the following options are correct?

Which plot is the adsorption isobar for chemisorption ?

Which of the following statements is false during adsorption of gas molecule on a metal surface?

The mass of Haemoglobin in $\mathrm{mg}$ required to protect from coagulation of $50 \mathrm{mL}$ of a gold sol on adding $5 \mathrm{mL}$ of $10\% \mathrm{NaCl}$ solution is: (gold number of Haemoglobin $=0.03$)

The trend in the colligative properties for the same concentration of ${\mathrm{BaCl}}_2, {\mathrm{MgCl}}_2$ and $\mathrm{NaCl},$ respectively, is

The most effective coagulating agent among the options for ${\mathrm{Sb}}_2{\mathrm{S}}_3$ sol is
