Chemisorption involves high activation energy and increases to a maximum value with rise in temperature.
Rate of physisorption increases with decrease in temperature increase in temperature decrease in pressure decrease in surface area
Velocity of sound in air (i) increases with temperature (ii) decreases with temperature (iii) increases with pressure (iv) is independent of pressure
How can pressure be increased or decreased?
Velocity of sound in air I. Increases with temperature II. Decreases with temperature III. Increase with pressure IV. Is independent of pressure V. Is independent of temperature Choose the correct answer
How does entropy changes with a. Increase in temperature b. Decrease in pressure?
In the case of chemisorption, why adsorption first increases and then decreases with temperature?
