1.	Based on entropy Change predict a spontaneous reaction among the following. (A): (NH_(4))_(2)CO_(3)(s) to 2NH_(3)(g)+CO_(2)(g) +H_(2)O(l)and (B):NH_(3)(g)+H_(2)S(g)to NH_(4)HS_((s).
Answer» Solution : Reaction .A. is spontaneous based on the entropy change. One mole of SOLID AMMONIUM carbonate gives three moles of gascous PRODUCTS, there by INCREASING the DISORDERLINESS and entropy. The entropy change is positiye.
