Given the following heat of formation values, calculate the heat of reaction for the following:
C ₃H ₈( g ) + O ₂( g ) → CO ₂( g ) + H ₂O( l ) .
Δ H _fvalue in kJ\mol for C ₃H ₈( g ) is − 103.8, for O ₂( g ) is 0, for CO ₂( g ) is − 393.5, and for H ₂O( l ) is − 285.8.

The heat of reaction is calculated using the formula: ΔH_reaction = ΣΔH_f(products) - ΣΔH_f(reactants). For the given reaction, the balanced equation is C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(l). The calculation is: [3(-393.5) + 4(-285.8)] - [-103.8 + 5(0)] = -2220 kJ.
