Question

The normal combustion heat of graphite is of ΔcH0 = -94.05 kcal/mol. The molar heat capacities of reactants and products vary this way between 298-1273 K (in cal /(mol K)) :
 

molar heat capacities of reactants and products vary this way between
298-1273 K (in cal /(mol K)) :
C, (grafito) = 4.1+1.02 ×10³T – 2.11×10°T²
C, (CO,) = 7.7+5.3×10-³T – 0.83× 10“T²
C, (0,) = 8.27+0.258×10-³T – 1.877×10°T²
Which is the combustion heat at 1000K?
