Question

(a) Calculate the enthalpy change, ΔrH°, for the formation of 1.00 mol of strontium carbonate (the material that gives the red color in fireworks) from its elements.                                                                                                          Sr(s) + C(s) + 3/2  O2(g) → SrCO3(s)
The experimental information available is
Sr(s) +1/2 O2(g) → SrO(s)
ΔfH°' = -592 kJ/mol-rxn
SrO(s) + CO2(g) → SrCO3(s)
ΔrH°  = -234 kJ/mol-rxn
C(graphite) + O2(g) → CO2(g)
ΔfH° = -394 kJ/mol-rxn
(b) Draw an energy level diagram relating the energy quantities in this problem.
