Consider the following graph between the extent of adsorption (x/m) and pressure: What is the correct relation between T1, T2 and T3?a.T1>T2>T3b.T3<T2<T1c.T1<T2<T3d.None of the above

Freundlich adsorption isotherm is given by the expression x/m = KP1/n. Which of the following conclusions can be drawn from this expression?a.When n = 0, plot of x/m vs p is a curve.b.When 1/n = 0, the adsorption is independent of pressure.c.When 1n = 0, the adsorption is directly proportional to pressure.d.When n = 0, x/m vs p graph is a line parallel to x-axis.

In which of the following cases does adsorption occur more readily?a.Low temperature and high pressureb.High temperature and high pressurec.Low temperature and low pressured.High temperature and low pressure

In Langmuir’s model of adsorption of a gas on a solid surface:a.The mass of gas striking a given area of surface is independent of the pressure of the gas.b.The amount of gas striking a given area is proportional to the pressure of the gas.c.The adsorption at a single site may involve multiple molecules at the same time.d.The rate of desorption does not depend on the surface covered.

Extent of adsorption (xm) decreases with increase in temperature.

When the temperature is lowered and pressure is raised, the adsorption of a gas on a solida.Increasesb.Remains unaffectedc.Decreasesd.Decreases first then increases
