what is the heat of combustion of ethane, c2h6, in kilojoules per mole of ethane? enthalpies of formation can be found in the

Respuesta :

The heat of combustion of ethane is -1559.7 J/mol.

The equation of the reaction is;

2C₂H₆ (g) + 7O₂ (g) ⟶ 4CO₂ (g) + 6H₂O (l)

Hence;

ΔH°reaction = [4(-393.5) + 6(-285.8)] - [2(-84.7) + 7(0)]

ΔH°reaction =[(-1574) + (-1714.8)] + 169.4

ΔH°reaction = -3119.4 J/mol

If 2 moles of C₂H₆ produces -3119.4 J/mol

1 mole of C₂H₆ produces -1559.7 J/mol

What is the heat of combustion?

  • The heating fee (or electricity price or calorific value) of a substance, usually a fuel or food (see meals power), is the amount of heat launched at some stage in the combustion of a unique amount of it.
  • The calorific fee is the entire strength released as heat while a substance undergoes complete combustion with oxygen below widespread conditions.
