Question
Adsorption of gases on solid surface is exothermic because :(a) free energy increases(b) entropy decreases(c) entropy increases(d) interaction developed between gas and solid particles
Step 1
This interaction leads to a decrease in the randomness or entropy of the gas molecules. This can be represented as $\Delta S$ (change in entropy). Show more…
