Calculate difference, ΔH-ΔE=Δ(PV) for the combustion reaction of 1 mole of heptane. (Assume standard state conditions and 298 K

Mamont248 [21]

Answer:

ΔPV = -9911 J

Explanation:

The combustion of 1 mole of heptane is:

C₇H₁₆(l) + 11O₂(g) → 7CO₂(g) + 8H₂O(l)

The change in number of moles of gas molecules is:

Δn = 7 moles products - 11 moles reactants = -<em>4 moles</em>

Using ideal gas ΔPV is:

ΔPV = ΔnRT

Where:

Δn is -4mol

R is 8,314472 J/molK

T is 298K

Replacing:

<em>ΔPV = -9911 J</em>
