The sign of Δ S ∘ is to be predicted in each case. Concept introduction: Entropy ( Δ S ∘ ) is the measure of degree of disorder or randomness. Increase in the randomness of the system leads to increase in the entropy (entropy is positive). The sign of entropy depends on the number of moles. If number of moles decreases, then sign of the entropy will be negative whereas, if the number of moles increases, the sign of entropy will be positive.
