Question

why easily liquefiable gases are readily absorbed by physisorption ​

Answer 1

Answer:

In general easily liquefiable gases (i.e. with higher critical temperature) are readily adsorbed as the form large number of weak van der waal forces. The gas having lower critical temperature than room temperature will exist in gaseous form at room temperature. So to liquefy it we need to decrease the temperature.
