Question 1

Using the information below, calculate ΔHf° for PbO(s)
              PbO(s) + CO(g) → Pb(s) + CO2(g)     ΔH° = –131.4 kJ
              ΔHf° for CO2(g) = –393.5 kJ/mol
              ΔHf° for CO(g) = –110.5 kJ/mol

–151.6 kJ/mol
–283.0 kJ/mol
+283.0 kJ/mol
–372.6 kJ/mol
+252.1 kJ/mol

Question 2

What is the enthalpy change when 41.8 mL of 0.530 M sulfuric acid reacts with 21.5 mL of 0.175 M potassium hydroxide?
H2SO4(aq) + 2KOH(aq) → K2SO4(aq) + 2H2O(l)
ΔH° = –111.6 kJ/mol
 


–0.210 kJ
–2.89 kJ
–2.47 kJ
–0.420 kJ
–112 kJ
