Predict the sign of the entropy change, ΔS∘, for each of the reaction displayed.

Drag the appropriate items to their respective bins.

Pb2+(aq)+2Cl−(aq)→PbCl2(s)

CaCO3(s)→CaO(s)+CO2(g)

2NH3(g)→N2(g)+3H2(g)

2Mg(s)+O2(g)→2MgO(s)

C5H12(g)+8O2(g)→5CO2(g)+6H2O(g)

H2O(l)→H2O(g)

Positive Negative

♦ Relevant knowledge
Entropy Change is the phenomenon which is the measure of change of disorder or randomness in a thermodynamic system. It is related to the conversion of heat or enthalpy done in work. A thermodynamic system which has more randomness means it has high entropy.
