Question: Calculate So for the following reactions, using standard entropy values. a. Pb(s) + 1/2O2(g) PbO(s) b. CS2(g) + 4H2(g) CH4(g) + 2H2S(g) c.

Calculate ∆So for the following reactions, using standard entropy values.
a. Pb(s) + 1/2O2(g) → PbO(s)
b. CS2(g) + 4H2(g) → CH4(g) + 2H2S(g)
c. C2H4(g) + 3O2(g) → 2CO2(g) + 2H2O(g)
d. Ca(s) + 2HCl(aq) → CaCl2(aq) + H2(g)
