With respect to enthalpy of combustion which of the following is correct? |
| A. | ∆H<sub>rxn</sub> = Σ∆H<sub>f</sub> (product) – Σ∆H<sub>f</sub> (reactant) |
| B. | ∆H<sub>rxn</sub> = Σ∆H<sub>f</sub> (reactant) – Σ∆H<sub>f</sub> (product) |
| C. | ∆H<sub>rxn</sub> = Σ∆H<sub>f</sub> (product) + Σ∆H<sub>f</sub> (reactant) |
| D. | ∆H<sub>rxn</sub> = 2 Σ∆H<sub>f</sub> (product) – Σ∆H<sub>f</sub> (reactant) |
