WebThe reaction is as follows: Ba (OH) 2 * 8 H 2 O + 2 NH 4 SCN -> Ba (SCN) 2 + 2 NH 3 + 10 H 2 O. The large increase in the entropy of the system (495 J/mol K) is a result of the large number of molecules present in the sum of the products. This increase in entropy overcomes the endothermicity (102.2 kJ) of the system, so the reaction is spontaneous.
