  • c)
    G increases
  • d)
    S decreases
Correct answer is option 'D'. Can you explain this answer?

For spontaneous absorption ΔG is negative as well as the degree of randomness of gas molecules
decreases thereby ΔS also negative. That’s why T.ΔS is –ve
 ∴ ΔH = ΔG + T.ΔS
Thereby ΔH is –ve

  • Adsorption of gas on the solid metal surface is spontaneous and exothermic, then ΔS decreases.
  • Since for spontaneous and exothermic process, ΔG = −ve, ΔH = −ve at all temperatures.
  • Therefore, from ΔG = ΔH − TΔS,ΔS should be −ve.
  • Also, the adsorption of a gas on a solid surface gives a more orderly arrangement.
