Explain Entropy and spontaneity of the process, with examples.

Assertion : If both DeltaH^(@) and DeltaS^(@) are positive then reaction will be spontaneous at high temperature. Reason : All processes with positive entropy change are spontaneous.

Explain entropy and spontaneity of the process.

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) .
