Question 1

The most common white pigment until the 1880s was lead white, sometimes called basic lead carbonate: (PbCO3)2Pb(OH)2. Paintings containing lead white turned black in the presence of moist H2S from natural sources and polluted air due to the formation of PbS. The PbCO3 portion of this reaction is shown below.

PbCO3(s) + H2S(aq) → PbS(s) + H2CO3(aq)


If ΔH° = -60.9 kJ/mol and ΔS° = 26.6 J/K, what are ΔSsurr and ΔStotal for this reaction at 25°C?

Question 2

For the reaction N2(g) + O2(g) → 2 NO(g), ΔH° = 180.4 kJ/mol and ΔS° = 24.9 J/K. ΔStotal for this reaction is ________ J/K, and the reaction is ________ (spontaneous, nonspontaneous) at 25°C.
