Explanation / Answer

we have:

Sof(HCl(g)) = 186.908 J/mol.K

Sof(NaOH(s)) = 64.455 J/mol.K

Sof(NaCl(s)) = 72.13 J/mol.K

Sof(H2O(l)) = 69.91 J/mol.K

we have the Balanced chemical equation as:

HCl(g) + NaOH(s) ---> NaCl(s) + H2O(l)

deltaSo rxn = 1*Sof(NaCl(s)) + 1*Sof(H2O(l)) - 1*Sof( HCl(g)) - 1*Sof(NaOH(s))

deltaSo rxn = 1*(72.13) + 1*(69.91) - 1*(186.908) - 1*(64.455)

deltaSo rxn = -109.323 J/K

Answer: -109.323 J/K
