Explain your answer please !!​

Answer 1

Answer:

hey dear ----

A is correct ✅✅✅✅

solution...

After adsorption these is decrease in the residual forces due to bond formation. \[\Delta G,\Delta H\And \Delta S\]all are negative in the case of adsorption,...

hope it's helpful for you

Answer 2

Answer

(c) On adsorption, the residual forces on the surface are increased.

★Explanation★

After absorption there is decrease in a residual forces due to Bond formation.

∆G , ∆H and ∆S , all are negative in the case of adsorption.
