4.13.3.3. Example: Char combustion

\[\text{C}(s) + 0.5 \text{O}_2 (g) → \text{CO}(g)\]

Notes:

• Species database names and aliases are defined on single lines.

• The heat of reaction is defined.

• The gas phase receives 20% of the heat of reaction.

• Solids phase 1 receives 80% of the heat of reaction.
