320809 Which gas will be adsorbed on a solid to greater extent?

1 A gas having non polar molecule
2 A gas having the highest critical temperature \(\left(\mathrm{T}_{\mathrm{c}}\right)\)
3 A gas having the lowest critical temperature
4 A gas having the highest critical pressure

320810 In an adsorption experiment, a graph between \({\mathrm{\log (x / m)}}\) versus \({\mathrm{\log P}}\) was found to be linear with a slope of \({\mathrm{45^{\circ}}}\). The intercept on the \({\mathrm{y}}\) axis was found to be 0.301 . Calculate the amount of the gas adsorbed per gram of charcoal under a pressure of 3.0 atm .

320811 In Langmuir's model of adsorption of a gas on a solid surface

1 The mass of gas striking a given area of surface is proportional to the pressure of the gas
2 The adsorption at a single site on the surface may involve multiple molecules at the same time
3 The rate of dissociation of adsorbed molecules from the surface does not depend on the surface covered
4 The mass of gas striking a given area of surface is independent of the pressure of the gas

320812 The gas that is adsorbed to a larger extent on charcoal is

1 \(\mathrm{H}_{2}\)
2 \(\mathrm{CO}_{2}\)
3 \(\mathrm{CO}\)
4 \(\mathrm{NH}_{3}\)
