Given reaction is
2Al(s)+3ZnO(s)-->Al2O3(s)+3Zn(s)
ΔS rxn = sum of ΔS (products) - sum of ΔS (reactants)
the standard values of entropy change are
ΔS Al2O3(s) = 50.99 J/K mol
ΔS ZnO = 43.9 J/K mol
ΔS Al = 28.3 J/K mol
ΔS Zn = 41.6 J/K mol
ΔSrxn = [ΔSAl2O3 + 3 X ΔSZn] -[2X ΔSAl + 3 X ΔSZnO]
Putting values
ΔSrxn = [50.99 + 3 X 41.6] -[2 X 28.3 + 3 X 43.9] = 175.79 - 188.3 = -12.51J /K mole

Entropy, denoted by the symbol S, is the thermodynamic property describing the amount of molecular randomness or disorder in a system. It is a state thermodynamic function, meaning that its value does not depend on the path used to arrive at a specific set of conditions. Each system with a specified temperature, pressure, and composition has a unique entropy value. The entropy change, ΔS, is the difference in entropy between two states of a system, such as between the reactants and...
