Derive the variation of x/m versus temperature for physical adsorption process. Explain the nature of the curve.

For a given mass of gas the variation of pressure versus temperature is shown in the figure. What is the ratio of volume of the gas at points A and B. .

Explain the variation of conductivity with temperature for ionic conductors.

The curve showing the variation of pressure with temperature for a given amount of adsoption is called

Following is the variation of physical adsorption with temperature.

Physical adsorption is appeciable at…………….temperature,

Explain the following observations. a. Sun looks red at the time of sunset. b. Rate of physical adsorption decreases with rise in temperature.

Assertion : Physical adsorption increases with increase in temperature. Reason : Physical adsorption is an endothermic process.

Observe the given adsorption isotherm carefully and choose the correct option (i) These curves indicates that at a fixed temperature, there is a decrease in physical adsorption with increase in pressure. (ii) These curves always seem to approach saturation at high pressure. x/m=k*p^(1//n) (n gt 1) is generally represented by this isotherm. (iv) These curves indicate that at a fixed pressure, there is a decrease in physcial adsorption with increase in temperature .

Which one of the following statements is wrong? a. Physical adsorption of gas directly related to its critical temperature. b. Chemical adsorption decreases regularly as the temperature is increased. c. Adsorption is an exothermic process. d. A solid with a rough surface is a better adsorbent than the same solid with a smooth surface.

Which of the following represents correctly the variation of degree of adsorption against temperature for physical adsorption ?
