What is the effect of increasing temperature on the amount of gas adsorbed in physical adsorption?
The amount of gas adsorbed increases with increasing temperature
The amount of gas adsorbed decreases with increasing temperature
The amount of gas adsorbed remains constant with increasing temperature
The effect of temperature cannot be predicted on the amount of gas adsorbed in physical adsorption
Physical adsorption is an exothermic process, and increasing the temperature favors the reverse process of desorption. Therefore, as the temperature increases, the amount of gas adsorbed decreases.
