    More is the number of gaseous components more is degree of randomness and hence more is the entropy
  • Dinesh khalmaniya thankyou
    option a actually randomness increase, entropy increase. order of randomness will be gas>liquid>solid so if solid change to liquid or gas then randomness increase and hence entropy...

    The (a) I'd accompanied by a decrease in entropy. Because number of moles of gaseous compounds have decreased. Entropy is randomness. More the number of moles of gaseous components...
