Use each equation to predict whether the relative entropy change is S(products) > S(reactants) or S(products) < S(reactants) and whether ΔS > 0 or ΔS < 0 for the chemical reaction represented. Justify your answer in each case. a. 2NH3(g)→N2(g) + 3H2(g) b. 2Al(s) + 3F2(g)→2AlF3(s)

a. S>0 (Because Ammonia is stable at ordinary temperature. b.S<0(means heat is evolved) Because Fluorine is readily reactive!

For a. the entropy change ΔS>0 due to the S(products)>S(reactants) As it can be seen 2 moles of gas are being converted to 4 moles of gas which is an increase in ΔS. For b. ΔS<0 due to S(products)
