Vedclass · Answer

(C) $1$. Adsorption is a surface phenomenon involving the release of energy,making it an exothermic process $(\Delta H < 0)$.
$2$. Physisorption involves weak van der Waals forces and is reversible. It decreases with an increase in temperature.
$3$. Chemisorption involves strong chemical bonds and is often irreversible. It initially increases with temperature due to the requirement of activation energy.
$4$. Therefore,the statement that 'Physisorption increases with an increase in temperature' is incorrect,as physisorption typically decreases as temperature rises.
