As we learn

Change in entropy during adsorption -

When a gas is adsorbed, the freedom of movement of its molecule becomes restricted. This amounts to decrease in the entropy of the system.

-

 

 We know that for adsorption \Delta H = -ve and \Delta S = -ve. Do not worry about krypton or xyz focus onward adsorption.
