Spontaneous attraction of a gas molecules on solid surface is an exothermic process because 1.)∆H increases for system 2.)∆S increases for gas 3.)∆S decreases for gas. 4.)∆G increases for gas

This best describes for the adsorption process and hence from
G = H – TS
the G should be negative.
And during the process the randomness decreases hence S should be negative too.
