उत्तर
In chemical adsorption, the adsorption first increases and then decreases with an increase in temperature.
Explanation:
This happens because at lower temperatures, the activation energy is high and the adsorption rate is slow, but as temperature increases, adsorption becomes more favorable up to a point. Beyond that, higher temperature causes desorption, leading to a decrease in adsorption. Hence, adsorption rises initially due to increased reaction rate and then falls due to desorption at higher temperatures.
