How does chemisorption vary with temperature?
Advertisements
उत्तर
Effect of temperature on chemisorption: Even though chemical adsorption is an exothermic process, but like most chemical changes, the extent of chemisorption increases with increase in temperature up to a certain limit and then after that, it starts decreasing.
