Question

Use the following reactions to answer the next two questions.

  1.       4PbO (s) → 4Pb (s) + 2O2 (g)                      ∆H° = 876 kJ
  2.       C (s) + O2 (g) → CO2 (g)                               ∆H° = -394 kJ
  3.       3PbCO3 (s) → 3PbO (s) + 3CO2 (g)              ∆H° = 258 kJ

 

A)

Calculate ∆H° for the reaction:

2PbCO3 (s) → 2Pb (s) + 2C (s) + 3O2 (g)

 

B)Calculate the enthalpy change, ∆H° (in kJ) that is involved in the production of 2.50 gram of solid carbon
